When will this impact me?
US 15, Catoctin Mountain Highway
Location of Project:
TC11 - BRIDGE 10098 ON MOTTER AVENUE
Replace Bridge 10098 on Motter Ave.
Notice: The Motter Avenue Bridge over US 15 is closed to pedestrians due to construction. Pedestrians should use the temporary pedestrian bridge. (
The Motter Avenue Bridge over US 15, originally constructed in 1957, is structurally safe, but the concrete deck has deteriorated to the point where it requires replacement. Additionally, the bridge is classified as functionally obsolete due to its lack of shoulders and high volume of traffic. As a result of this functional obsolescence, and proposed future widening along US 15 under the bridge, the decision was made to completely replace the bridge.
To view a PDF of the project design,
The replacement bridge will be constructed wide enough to accommodate the current four lanes of through traffic, a continuous left turn lane to accommodate vehicles turning from Motter Avenue onto the entrance ramps to US 15, and a dedicated lane for traffic entering Motter Avenue from US 15 northbound and proceeding north in the direction of Fort Detrick. Pedestrian sidewalks will be included in both directions across the new Motter Avenue Bridge. The acceleration and deceleration lanes on US 15 will be lengthened, and the new bridge will be long enough to accommodate proposed future widening of US 15.
SHA has also partnered with the City of Frederick to include widening of Motter Avenue/Opossumtown Pike from US 15 north to the intersection of Thomas Johnson Drive. These improvements will include the addition of a third lane in each direction along Motter Avenue/Opossumtown Pike, improvements to the intersection at Thomas Johnson Drive, and reconstruction of the signals at several intersections along Motter Avenue/Opossumtown Pike.
During construction, the existing two lanes of traffic in each direction will remain open. To accomplish this, the initial portion of the replacement bridge will be constructed north of the existing bridge. Once completed, it will be used to carry traffic while the existing bridge is removed and the remainder of the new bridge is constructed. Temporary, single-lane closures may be necessary during off-peak travel times, but two-way traffic will be maintained at all times. Pedestrian traffic will also be maintained on a separate temporary pedestrian bridge just north of the new construction.
SHA will make every effort to complete this project as quickly as possible while minimizing impacts to local residents and motorists. Construction began in spring 2012, and will be completed in fall 2014, weather permitting.
