The impacts of transportation networks on early urban development are reflected in the growth of Alexandria. Alexandria merchants financed a transportation network into the backcountry or "hinterland," the farmland west of the Fall Line. Before the Civil War, the city connected its wharves and its stores to farms in the Piedmont - and then to the Shenandoah Valley.
Investments in turnpikes, harbor improvements, canals, and railroads made Alexandria into an economically successful city. Despite the transfer of government responsibility for the city to the District of Columbia and back again, Alexandria was able to outcompete Georgetown across the river as well as Occoquan, Dumfries, and Fredericksburg in Virginia.
Alexandria expanded its wharf space from the natural riverbank deeper into the Potomac River, in part by sinking old ships and dumping dirt between piers that had extended out into the river - and in 2016, one of those ships was uncovered during excavation for the new Indigo Hotel

Alexandria and Dumfries were chartered on the same day in 1749. Both were sponsored by Scottish merchants with comparable economic interests. The towns even have the same pattern of colonial street names - Prince, Duke, etc. Within 25 years after the initial founding date, Alexandria was thriving while Dumfries had already faded into obscurity.

Dumfries failed to build roads, canals, or railroads to facilitate farmers bringing crops to their docks. Dumfries also failed to prevent soil erosion from silting up the harbor, which is traditionally cited as the reason for the town from failing to grow.
Dumfries business largely ceased when the port was filled with sediment. Efforts to dredge a channel or move downstream failed, and the "Newport" community of townhomes on the south bank is the only modern evidence of the attempt. Dumfries literally became a backwater. The shoreline migrated east as silt filled the old harbor, and the original wharves of Dumfries are now located between the two halves of US 1 running through town.
Dumfries was located at the head of navigation on Quantico Creek, until excessive sediment silted up the harbor

Alexandria merchants linked their port first with farmers in western Fairfax and Loudoun counties. In the 1790's, the city initiated and financed the Little River Turnpike to Aldie, where the Little River cuts through the Blue Ridge. From Alexandria to Jermantown (near the Fairfax campus of George Mason University), the route of the turnpike follows modern US 236. From Jermantown modern US 50 traces the historic turnpike route to Aldie, at the base of the Blue Ridge. The Ashby Gap Turnpike Company later extended the connection west to the crest of the Blue Ridge.

The Little River Turnpike was the first successful turnpike in the South. The Philadelphia-Lancaster turnpike, drawing the trade of farmers in southeastern Pennsylvania to Philadelphia and away from Baltimore, was the first successful toll road in North America.

Even after paying the toll, farmers throughout western Fairfax and Loudoun counties who used Little River Turnpike could make a greater profit. The road reduced the time required to transport wheat and other bulky items to the port, where competition was greater. Ships from Alexandria could carry farm products to multiple markets, including Europe. Prices for Piedmont farmers were higher, while Alexandria merchants benefited from increased economic activity in their city.

Alexandria's next target was the agricultural trade from Prince William, Fauquier, Culpeper, and Orange counties. City leaders initiated and, with some state funding, built the Warrenton-Alexandria turnpike. It was chartered in 1808 and built in two segments. The stretch from Jermantown on the Little River Turnpike to Buckland in western Prince William County was started in 1812, then completed in 1818 after the War of 1812 ended. The section between Buckland and Warrenton in Fauquier County was built between 1824-27.
The Stone Bridge was built over Bull Run in 1825. The Stone House, a landmark on what became the Manassas Battlefield, was constructed to collect tolls and support travelers moving between the Potomac and Rappahannock rivers.
Today that turnpike is US 29. On the old maps of Alexandria, Arlington, and Fairfax County, it is often referenced as the "Warrenton Turnpike." In Fauquier County, it was often described as the "Alexandria Turnpike." Local residents on one end of the road referred to the turnpike based on the destination at the other end.
the Stone House on Manassas Battlefield was originally a toll house for the Alexandria-Warrenton Turnpike
Alexandria merchants were part of the Patowmack Canal and the Chesapeake and Ohio (C&O) Canal initiatives. The C&O Canal originally ended in the competitive rival town of Georgetown, and the construction of a causeway to Mason's Island (now Theodore Roosevelt Island) after 1807 steered river traffic to Georgetown.1
Alexandria arranged for an extension of the C&O Canal to draw traffic to the deeper water port at Alexandria. The Alexandria Canal crossed the Potomac River on Aqueduct Bridge. It opened in 1843, after 10 years of construction. Canal boats finally could go between Alexandria and the C&O Canal while avoiding the risks of flooding, ice, and debris in the Potomac River.

During the Civil War, the water was drained and the bridge modified to allow for horse-drawn wagons and people to walk across the bridge. After the war ended, the superstructure of the Aqueduct Bridge was replaced with wooden Howe trusses and a platform was added on top. That made the structure a double-decked bridge, with boats below and wagons crossing the river on top.

Georgetown merchants got first crack at the trade coming down the canal, and Chesapeake Bay and Atlantic Coast traffic relying upon shallow water ships might stop at Georgetown. However, Alexandria was a more-attractive destination to those boats engaged in international trade to the Caribbean and Europe. Large ships could avoid navigating the shallow channel of the Potomac River and delays associated with draw bridges between Alexandria and Georgetown.

The canal operated between 1843-1886. A brick culvert was built underneath it at Rosslyn, allowing the ferry road to reach the causeway to Mason's Island. That culvert survived until demolition by the Virginia Department of Highways in the 1950's.

The Federal government purchased the bridge because the private owners were unable to repair it sufficiently. The wooden superstructure was replaced and the bridge opened in 1886 with iron trusses. The Federal government's modifications ended the opportunity for boats to cross the bridge.
The Great Falls and Old Dominion Railroad widened the Aqueduct Bridge in order to construct its trolley line from Georgetown to Rosslyn in 1903. That trolley line was extended to Great Falls in 1906.

The Aqueduct Bridge was closed to all traffic in 1923 when the new Key Bridge opened. The old bridge's superstructure was removed in 1933 by the Civil Works Administration during the Great Depression, but the Georgetown abutment was left intact. The bases of the eight piers were left in the river to protect Key Bridge from ice, but boaters complained that the remnants were a navigation hazard.
Seven of the eight piers were blasted away in 1962. The last pier next to the Virginia shoreline was retained as an historical artifact. Like the other piers, it rests on a foundation excavated 17 feet deep through the muddy river bottom to reach bedrock.2

When Alexandria was included within the boundaries of the District of Columbia in 1800-1846, there was no reason for Virginia politicians to support the economic growth of the city. Board of Public Works funding was restricted to projects within the boundaries of the state of Virginia, and Alexandria was not part of Virginia for nearly 50 years.
The state did not help to fund the Alexandria Canal, which linked Alexandria to the Chesapeake and Ohio Canal in 1843. Once the slice of Virginia within the District of Columbia was retroceded to Virginia in 1847, however, the state purchased Alexandria Canal bonds and relieved the town of much of that debt.3
in 1847, Alexandria lacked any railroad connection to the hinterland

Almost as soon as Alexandria was "revested" back to Virginia in 1847, the General Assembly chartered the Orange and Alexandria (O&A) Railroad. By 1851, the Orange and Alexandria stretched southwest from the port city through the Piedmont to Gordonsville. It attracted the farm trade of the backcountry more effectively than the Warrenton Turnpike. To allow trains to get to the Potomac River waterfront, the Wilkes Street Tunnel was cut through the bluff between St Asaph's Street and Fairfax Street.

With the O&A Railroad, Alexandria out-competed Fredericksburg's merchants. Fredericksburg tried to attract trade from the Piedmont farms by building a canal up the Rappahannock River, bypassing various rapids and allowing reliable transportation despite high/low water levels. However, the canal arrived after the railroad. By the time the Rappahannock Canal connected the Fall Line at Fredericksburg to Kellys Ford (near present-day Remington in Fauquier County), farmers in Orange, Culpeper, and Fauquier counties were already accustomed to shipping via the O&A Railroad to Alexandria.

In the "first to market" competition, Alexandria won. Fredericksburg did not become the preferred business center of the Piedmont, even where it was physically closer, because farmers in the Rappahannock River Valley grew accustomed to shipping goods via roads and railroads to Alexandria.
Fredericksburg was linked to the Potomac River and to Richmond by one of the first railroads in the state, but did not build a line west to Orange/Culpeper counties before the Civil War. Some grading was completed on the route of the planned Fredericksburg and Gordonsville Railroad, but it was an "unfinished railroad" during the war.

By the time Fredericksburg constructed the narrow-gauge Potomac, Fredericksburg & Piedmont (PF&P) in the 1870's, the economy of the Piedmont was tied tightly to Alexandria. The derogatory term "Poor Folks & Preachers Railroad" indicates that the PF&P was never a major freight route.4

Alexandria was not satisfied with just the trade from the Piedmont. The city's ambitions extended further west to the Shenandoah Valley and beyond.
Baltimore had obtained the business from the Potomac River watershed, by out-competing the Chesapeake and Ohio (C&O) canal and constructing the Baltimore and Ohio (B&O) Railroad. The city also took advantage of its deepwater port to attract the modern steamships. Baltimore benefitted from traffic that used the Winchester and Potomac Railroad connection linking Winchester to Harpers Ferry, but the Maryland-based investors focused on linking up to the Ohio River and getting traffic from across the Appalachian Mountains. The Baltimore and Ohio Railroad did not expand its network south of Winchester until after the Civil War, and Alexandria took advantage of the opportunity in the 1850's to capture the trade from south of Winchester.
A charter for the Manassas Gap Railroad authorized an independent line to run from Mount Jackson to Alexandria, with a branch reaching into southern Loudoun County between the Blue Ridge and the Potomac River.
the Manassas Gap Railroad proposed a branch through Loudoun County, but that potential competitor to the Alexandria, Loudoun and Hampshire Railroad was never built
Source: Library of Congress, Map of the Manassas Gap Railroad and its extensions; September, 1855
After the recession known as the Panic of 1857, construction of the Manassas Gap railroad was truncated. The independent line was connected to the O&A at a location named Manassas Junction, a name soon shortened to just "Manassas," and the branch into Loudoun County was never built.
The Alexandria, Loudoun, and Hampshire railroad (AL&H) was expected to bring coal traffic from Hampshire County (now in West Virginia) to Alexandria, in addition to the farm trade from the Winchester area. The last part of the AL&H route was abandoned in the 1960's after construction of Dulles Airport, and the route is now the Washington and Old Dominion (W&OD) bike path. The AL&H was never built across the physical barrier of the Blue Ridge beyond Bluemont, and the modern bike trail stops in Purcellville.

Though the Manassas Gap and AL&H railroads were not completed as planned, they demonstrate how Alexandria competed with Fredericksburg, the District of Columbia, and even Baltimore by building a better transportation system. Unlike Dumfries and Fredericksburg, Alexandria connected its international port with the "hinterland," the surrounding region capable of supplying goods and purchasing items from the central city.

Alexandria won the shipping competition with Fredericksburg, Dumfries, and Georgetown, but lost the most valuable backcountry trade to Baltimore. The Baltimore and Ohio (B&O) Railroad reached Harpers Ferry and completed the Winchester and Potomac Railroad in 1836. That railroad diverted the northern (lower) Shenandoah Valley trade away from Alexandria to the port of Baltimore.
The Baltimore and Ohio Railroad reached the coal fields of Cumberland, Maryland in 1842, directing that freight to the Maryland port rather than to Alexandria. The Chesapeake and Ohio (C&O) Canal did not begin to carry coal to Alexandria until 1850.
Alexandria continued to ship products using slave labor, but without adding value through processing or manufacturing in the city. Baltimore relied upon free white men to work in factories, and that city expanded as an industrial town as well as a shipping center.
Alexandria no longer serves now as a major port handling shipments inland to the western frontier; just tourist boats dock at its wharf today. The ferry that used to carry Baltimore and Ohio Railroad cars across the Potomac River was replaced by the Washington and Alexandria Railroad Bridge in 1863. That bridge was later removed, and the boxcar ferry is no longer operational. The waterfront next to the Wilkes Street tunnel originally completed by the Orange & Alexandria Railroad in 1856 has been converted from industrial to residential use.5
Multiple railroads served Alexandria. The Baltimore and Ohio Railroad had direct access to the city during the Civil War, hauling cars across the government bridge over the Potomac River. In 1870, the Pennsylvania Railroad ended its rival's monopoly of rail traffic into Virginia, and got the government to grant it exclusive rights to use the Long Bridge. To maintain its link, the Baltimore and Ohio Railroad built a 12.5 mile spur line from Hyattsville, Maryland through the District of Columbia to Shepherds Landing on the shoreline of the Potomac River.
From 1874-1906, the railroad used the Alexandria Branch to reach the river and carfloats to carry freight across the Potomac to Alexandria. That inefficient process ended in 1906, when the different railroads opened Potomac Yard and interchanged traffic there.
An "Emergency Bridge" was constructed in 1942 to handle the extra troop traffic in World War II, and to provide continuity of operations if the Long Bridge was made unusable by accident or saboteurs. It stretched 3,360 feet from the District of Columbia to Alexandria's shoreline at Third Street, next to Potomac Yard. That bridge was used between November 1942-1945, and was demolished in 1947.6

The Alexandria merchants still rely upon "internal improvements" to connect Northern Virginia to external factories and markets, but many goods arrive in town on trucks that use interstate highways.
When the Washington Post started shipping newsprint by rail instead of ship to its Robinson Terminal several years ago, Alexandria lost its last major freight operation. The coal-fired power plant generating electricity in Alexandria was supplied by train until the facility, known originally as the Potomac River Generating Station, was closed by GenOn Energy in 2012.
Two major railroads (the modern CSX) and the modern Norfolk Southern (incorporating the historic Orange and Alexandria and Manassas Gap railroads) connect the Ohio River valley with various cities on the Eastern seaboard. Those railroads deliver goods from the interior of North America to ocean-going ships at the ports of New York/New Jersey, Baltimore, Newport News, and Norfolk - but not Alexandria. The city is no longer dependent upon railroads, turnpikes, or canals to transport raw materials to urban factories or to ship manufactured products to rural customers.

Today, Alexandria's transportation network is designed to facilitate moving passengers by car and by three rail systems. Amtrak provides long-distance travel, Virginia Railway Express services commuters from Northern Virginia, and Metrorail provides local service.
