Reston Parkway Part of VDOT Bridge Repairs in 2016

Repairs to Reston Parkway’s bridge over the Dulles Toll Road will be part of a Virginia Department of Transportation’s (VDOT) $5.6 million project next spring.

VDOT says it will be performing preventative maintenance projects on bridges on Monroe Street, the Herndon-Monroe Park and Ride Ramp and Reston Parkway in advance of Metro’s Silver Line Phase 2, which is currently under construction.

The main purpose of the project is eliminating and closing the bridge deck joints above the Silver Line tracks. Doing it before Phase 2 opens in 2019 will save VDOT money in the end, the department says.

“Future construction of the tracks in the median of Route 267 (the Dulles Toll Road) will limit the access to the bridge existing piers,” VDOT said in a statement. “The cost of performing any future repairs to the bridge piers would need to include cost of coordination with Metro, which would significantly increase future repair costs.”

The Reston Parkway dual bridges over the Toll Road are 385-foot.-long, six-simple- span, steel plate girder bridges.

The northbound bridge was constructed in 1959 and widened and deck-replaced in 1989. The northbound total bridge width is 42.33 feet and consists of a 1.66-foot raised median, one-foot shoulder, three 12-foot traffic lanes, two-foot shoulder and 1.66-foot barrier.

The southbound bridge was constructed in 1976 and widened in 1989. The southbound total bridge width is 51.66 feet and consists of a 1.66-foot raised median, one-foot shoulder, three 12-foot.traffic lanes, three-foot shoulder, 1.66-ft. barrier, 8.33-foot. path and one-foot curb with pedestrian fence.

The Monroe Street/Van Buren Street dual bridges over the Toll Road are 378-foot-long, six-single-span, steel plate girder bridges. There is a 38-foot gap between the northbound and southbound bridges. The northbound bridge was constructed in 1963, and the deck was milled and overlaid in 1989. The southbound bridge was constructed in 1989.

The Herndon-Monroe Park and Ride Ramp bridge is a 613-foot-long, seven-single-span, steel plate girder bridge. The bridge was constructed in 1999.
