(Redirected from Interstate 66 (Virginia))

'Interstate 66' (abbreviated 'I-66') is an interstate highway in the eastern United States. As indicated by its even route number, it runs in an east-west direction. Its western terminus is at Middletown, Virginia, at an intersection with Interstate 81^[2]; its eastern terminus is at Washington, DC, at an intersection with U.S. Route 29.^[3]

Virginia

Because I-66 is the only major highway running west from Washington, D.C., into Northern Virginia, traffic on the road is often extremely heavy. For decades, there has been talk of widening I-66 from 2 to 3 lanes each way inside the Capital Beltway (Interstate 495) through Arlington, Virginia, although many Arlington residents are adamantly opposed to this plan. The Virginia Department of Transportation (VDOT) is studying the prospect of implementing this one-lane extension on westbound I-66 within the Beltway (thus alleviating congestion for people commuting away from DC).^[4]
Due to heavy commuter traffic, I-66 features High-occupancy vehicle (HOV) lanes in varying degrees. Between the Prince William Parkway (State Route 234) in Gainesville, Virginia and the Beltway, the left lane on eastbound I-66 is reserved for HOV-2 during morning rush hour (5:30 a.m. to 9:30 a.m.), and the left lane on westbound I-66 is reserved for HOV-2 during evening rush hour (3:00 p.m. to 7:00 p.m.). Also during those rush hours, between Route 50 and the Beltway, the right-hand shoulder is available for use as a travel lane. ^[5] Within the Beltway (between the Beltway and the Theodore Roosevelt Bridge), the entire eastbound (inbound) roadway is reserved for HOV-2 and Dulles Airport traffic during morning rush hour (6:30 a.m. to 9:00 a.m.), and the entire westbound (outbound) roadway is reserved for HOV-2 and Dulles Airport traffic during evening rush hour (4:00 p.m. to 6:30 p.m.). This is not readily and easily enforced, since single-passenger vehicles are allowed to come onto the highway within the beltway in the direction of rush-hour traffic when they are intending to use the Dulles toll road at exit 67. These restrictions may result more in a displacement of rush-hour than in an alleviation; I-66 is observed as relatively clear where and when they are in place, and congested for some time before and after.
Between Vienna and western Arlington County, the Orange Line of the Washington Metro runs along the median of the interstate. Four stations (Vienna/Fairfax-GMU, Dunn Loring-Merrifield, West Falls Church, and East Falls Church) are located along this section.
I-66 east has two exits, one from each side of the carriageway, to the Inner Loop of I-495. One is a right exit, while one is a left exit; the latter is retained to make it easier for traffic to join the Inner Loop without having to weave across the entire carriageway. Also, there is no access from the Outer Loop of I-495 to I-66 east; traffic wishing to make this movement must use State Route 267 east.
I-66 is named the "Custis Memorial Parkway" east of the Capital Beltway in Virginia. The name commemorates the Custis family, several of whose members (including Martha Dandridge Custis Washington, George Washington Parke Custis, Eleanor (Nelly) Parke Custis Lewis and Mary Anna Randolph Custis Lee) played prominent roles in Northern Virginia's history.

District of Columbia

In Washington D.C., I-66 follows the 'West Leg' of the Inner Loop freeway. After crossing the Potomac River on the Theodore Roosevelt Bridge concurrent with US 50, the route quickly turns north, separating from US 50. The Interstate interchanges with E Street before passing beneath Virginia Avenue in a short tunnel, before interchanging with the Rock Creek Parkway and Pennsylvania Avenue. The route eventually comes to a dead halt at US 29 and 27th Street.
This is the only 2 digit Interstate to enter the District of Columbia (other than the 100 yards (100 m) or so that I-95 passes through DC on the Woodrow Wilson Bridge).

History

Virginia

As with many urban interstate highway projects, I-66 has encountered opposition from local citizen groups.
Most notably for I-66 was the construction through Arlington, Virginia, proposed in 1956. After the Virginia Department of Transportation (VDOT) (then known as the Virginia Department of Highways) acquired two sections of the former route of the Washington and Old Dominion Railroad to provide a right-of-way through Arlington for the new highway, the Arlington Coalition on Transportation (ACT) filed a lawsuit in Federal District Court in 1971 opposing the Arlington portion of the project. The group objected to that urban segment due to concerns over air quality, noise and community cohesion changes. In 1972 the U.S. Fourth Circuit Court of Appeals ruled in favor of ACT, technically blocking any construction. The U.S. Supreme Court upheld the ruling in favor of ACT later in 1972^[6].
The impasse was eventually broken when the parties agreed on experts to conduct air quality and noise studies for VDOT; the firm of ESL Inc., the expert hired originally by ACT, was agreed upon to be hired by VDOT. Then, U.S. Secretary of Transportation Coleman personally intervened in 1976 with negotiations to reach a compromise of a reduced highway width including a transit element.^[7][8]
Less controversial was the portion of the highway's route immediately west of Arlington. There, VDOT decided to curve the highway to bypass the City of Falls Church, increasing the interstate's length while sparing the city from the road's immediate environmental impacts.

District of Columbia

In Washington D.C., I-66 was planned to extend east of its current terminus along the 'North Leg' of the Inner Loop freeway. I-66 would have also met the eastern terminus of Interstate 266 at US 29, and the western terminus of the South Leg Freeway (I-695) at US 50; I-266 would have been a parallel route to I-66, providing more direct access to the North Leg from points west, while I-695 would have been an inner-city connector between I-66 and I-95.
The final plans for the North Leg Freeway, as published in 1971, outlined a 1.5-mile six-lane tunnel beneath K Street, between I-266/US 29 and New York Avenue, where the North Leg would emerge from the tunnel and join with the Center Leg Freeway (formerly I-95, now I-395); the two routes would run concurrently for 3/4 of a mile before reaching the Union Station interchange, where I-66 was planned to terminate.
Despite the plan to route the North Leg in a tunnel beneath K Street, the vitriolic opposition to previous, scrapped alignments for the D.C. freeway network, which included previous alignments for the North Leg Freeway, led to the mass cancellation of all unbuilt D.C. freeways in 1977, resulting in the truncation of I-66 at US 29.
No auxiliary routes were constructed. Interstate 266 was planned in northern Virginia and Washington, D.C. It was cancelled in 1972 due to community opposition and environmental concerns.
