Abstract:

The intersection of Gallows Rd. and Arlington Blvd. in Virginia's Fairfax County required separation. Tiedback retaining walls, which required only 18 in. instead of the 18-22 ft normally required for retaining walls, permitted use of adjacent ramps as traffic detours. Sheet piles were driven along the Arlington Blvd. alignment and the tiedback walls constructed as excavation proceeded. The bridge steel was installed directly on the tiedback bridge abutments that were constructed in the same manner.
