Project at a Glance
About the Project
In advance of the Metrorail Silver Line Phase II, VDOT initiated these Simple Bridge Preventive Maintenance Projects with the main purpose of eliminating and closing the bridge deck joints above the proposed Silver Line tracks. Future construction of the tracks in the median of Route 267 will limit the access to the bridge existing piers. 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 Monroe Street/Van Buren Street dual bridges over Route 267 are 378-ft.-long, six-single-span, steel plate girder bridges. There is a 38-ft. gap between the northbound and southbound bridges. The northbound bridge was constructed in 1963, and the deck was milled and overlaid in 1989. The total northbound bridge width is 29.16 ft. and provides 24 ft. curb-to-curb for two traffic lanes, 1.5-ft. safety walks and 1.08-ft. parapets with fences. The southbound bridge was constructed in 1989 with a total bridge width of 35.66 ft. and consists of a 1.66-ft. parapet with fence, 1.37-ft. shoulder, two 12-ft. traffic lanes, 1.37-ft. shoulder, 1.25-ft. parapet, five-ft. sidewalk and 1-ft. parapet with fence.
The Herndon-Monroe Park and Ride Ramp bridge over Route 267 is a 613-ft.- long, seven-single-span, steel plate girder bridge. The total bridge width is 32.75 ft. and consists of one 17.71-ft. traffic lane and 5.90-ft. shoulders. The bridge was constructed in 1999.
The Reston Parkway dual bridges over Route 267 are 385-ft.-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 ft. and consists of a 1.66-ft. raised median, one-ft. shoulder, three 12-ft. traffic lanes, two-ft. shoulder and 1.66-ft. barrier. The southbound bridge was constructed in 1976 and widened in 1989. The southbound total bridge width is 51.66 ft. and consists of a 1.66-ft. raised median, one-ft. shoulder, three 12-ft. traffic lanes, three-ft. shoulder, 1.66-ft. barrier, 8.33-ft. path and one-ft. curb with pedestrian fence.
Construction began in May 2016 and is scheduled for completion in fall 2017.
