To accommodate traffic increases and improve safety along Route 221 in Roanoke County, VDOT realigned a 0.75-mile segment of the roadway. Volkert provided comprehensive construction management and inspection services for the federally funded, $20-million construction project during 5 phases of construction.
The widening of Route 221 from 2 to 4 lanes increased capacity and the new alignment eliminated a dangerous curve. In addition, a new drainage system and 2 new stormwater management ponds improved roadway drainage.
Bridge construction included 2 new superelevated, prestressed- concrete, bulb-T beam bridges with cast-in-place decks; a bridge replacement consisting of steel beams, a cast-in-place deck, and a new double-barrel box culvert under Route 221.
Volkert provided construction management services including inspection, materials testing, schedule reviews and monitoring, budget monitoring, NOI reviews and recommendations, and utility and agency coordination.
Key challenges included extensive excavation and blasting next to residential areas and a major commuter route, protection of Back Creek, concurrent construction of 3 bridges and access to the new bridge locations, omissions from the steel schedule, temporary lane closures and traffic delays, and public communication.
Volkert worked with the contractor to make sure the safest and effective plans for blasting, access to the bridge sites, and delivery and setting of the structural concrete girders were implemented.
