Major Bridge Work in 2015; MD 195 (Carroll Avenue) over Sligo Creek and Sligo Creek Parkway – Community Advisory

Bridge work to support safety and mobility.

The MD 195 (Carroll Avenue) bridge over Sligo Creek and Sligo Creek Parkway is scheduled for major rehabilitation starting in the spring of 2015. The Maryland State Highway Administration (SHA) will replace the bridge deck, sidewalk, and railings, and rehabilitate major elements of the bridge, including the beams and columns that support the deck above the two arches. In order to complete the necessary work safely, the bridge will be closed and traffic will be detoured during construction.

For additional information, you are invited to attend a meeting on October 2, 2013. The informational workshop will acquaint the public with the project. Display boards will show operational and safety improvements, and SHA representatives will be available to discuss project issues and answer questions concerning construction. No formal presentation will be given. Feel free to arrive at any time and walk through at your own pace.

Why is the work necessary?

This work is part of SHA’s bridge system preservation program aimed at providing reliable facilities in a timely manner. It will ensure the continued safe operation of the bridge and extend the service life of the 81-year old structure. The bridge is eligible for inclusion in the National Register of Historic Places; therefore, SHA will make every effort to maintain the appearance of the bridge while still meeting current codes and safety requirements.

How will vehicle and pedestrian traffic be impacted?

During construction, SHA crews will close Carroll Avenue at the bridge and vehicles will be detoured. Pedestrian traffic will be maintained on a temporary bridge directly adjacent to MD 195 over Sligo Creek Bridge. Access to all residential, business, hospital and trail entrances adjacent to the work zone will also be maintained.

What detours will be in place?

Motorists north and south of MD 195 over Sligo Creek Bridge wishing to continue on MD 195 beyond the project site will be directed to a traffic detour utilizing Flower Avenue, Maplewood Avenue, Maple Avenue and MD 410 (Philadelphia Road). The detour length is 1.25 miles, and will be improved at several locations to accommodate the additional traffic – these locations include the intersections of Hilltop Road and Sligo Creek Parkway, Maplewood Avenue and Flower Avenue, and Old Carroll Road and Sligo Creek Parkway. Also, while Sligo Creek Parkway is closed to motorists on Sundays, motorists may use it as a detour route during the week and Saturday, reducing detour length to less than one mile. A separate detour utilizing only State-owned roadways will be in place for commercial trucks, and Montgomery County Ride-On Transit is evaluating alternatives to minimize impacts to the bus routes and bus stop locations during the closure.

Have any other alternatives been considered?

Project engineers considered constructing a temporary bridge to maintain one lane of vehicular traffic during construction. However, a temporary bridge to support vehicles would have to be larger than the proposed temporary pedestrian bridge, including approach roadways requiring an extensive clearing of wooded parkland adjacent to the bridge, and would add one year to the project. The chosen alternative will take the shortest time to construct and minimize the impacts to the surrounding environment.

What is the project schedule?

Construction is tentatively scheduled to begin in the spring 2015 and the bridge is anticipated to be closed for one year. Additionally, some construction will take place before and after the bridge is closed, but will be able to do so while it carries traffic. Work will not start until construction is completed on MD 650 (New Hampshire Avenue) over Sligo Creek Bridge. SHA will make every effort to complete this project as quickly as possible while minimizing impacts to local residents and motorists.
