Project Name:
MD 478, Knoxville Road

Location of Project:
BRIDGE 1008900 OVER BRANCH OF POTOMAC RIVER

Description:
Replace Bridge 1008900 over Branch of the Potomac River.
 
Scope:
The bridge on MD 478 (Knoxville Road) near Brunswick in Frederick County, is scheduled for replacement. Originally constructed in 1925, the bridge is safe for the traveling public, but is nearing the end of its useful service life. Should the deterioration continue, weight restrictions (reduced loads for trucks, school buses, and emergency vehicles) would need to be posted to ensure safety. This would have a significant impact on the area since it serves as a travel route between Brunswick and US 340 to the west. The new bridge will be widened to provide for shoulders and a sidewalk on the north side of the roadway will be added to improve safety for pedestrians. Replacing the bridge will save money on future maintenance spending, and support safety and mobility as a part of SHA’s bridge preservation program.

Several alternatives for maintaining traffic along MD 478 during construction were considered including detouring all traffic, maintaining a single lane of traffic controlled by a system of temporary signals to alternate traffic through the work zone, and construction of the new bridge on a new alignment. At this time SHA is pursuing a temporary detour as the preferred alternative.

SHA will make every effort to complete the project as quickly as possible while minimizing impacts to local residents and motorists. Construction is scheduled to begin Spring, 2018 and be completed Fall, 2019 weather permitting, although we only expect the detour to be in place for six months.
