Description

This project provides for the replacement of the existing Schaeffer Road Bridge over Little Seneca Creek. The existing Schaeffer Road Bridge, constructed in 1925, is a 44 feet 8 inches long single span steel beam with concrete deck structure carrying a 16-foot clear roadway and a one-foot 3-inch combined W-beam railing and two-strand-steel-pipe-rail concrete post barriers on both sides for a total out-to-out bridge width of 18 feet 6 inches. The structure is supported by two stone masonry abutments encased in concrete. The replacement Schaeffer Road Bridge will be an approximately 42 feet 6 inches long single span simply supported prestressed concrete slab beam structure carrying a 16-foot clear roadway and one 2 feet 6 inches wide, 3 feet 6 inches high CalTrans Type 85 concrete parapet with two steel pipe rails on both sides, for a total out-to-out bridge width of 21 feet. The proposed bridge will be supported by two concrete abutments with concrete footing and drilled shaft foundations. Approximately 194 feet long asphalt approach roadway will be repaved to tie the bridge to the existing roadway. The existing gravel parking area at the southeast corner of the bridge will be reconstructed to be an asphalt parking area.

Capacity

The roadway Average Daily Traffic (ADT) is approximately 420 vehicles per day on weekdays and approximately 500 vehicles per day on weekends.
anchor

Estimated Schedule

Design of the project is expected to be completed in FY25. Construction is scheduled to start in FY26 and be completed in FY27. The bridge will be closed to traffic during the school summer break of 2026.

Justification

The 2021 inspection revealed that the stone masonry abutments encased in concrete are in poor condition. This bridge is considered structurally deficient. The bridge is posted for a weight restriction of 50,000 lbs. for single unit trucks and 64,000 lbs. for combination unit trucks due to the live load rating analysis for the bridge. The proposed bridge replacement is necessary to continue to ensure a safe roadway condition for the traveling public.

Other

The 2023 Rustic Roads Functional Master Plan designates Schaeffer Road from White Ground Road to Burdette Lane as a rustic Road. The 2018 Montgomery County Bicycle Master Plan does not recommend a bicycle facility. The Schaeffer Road Bridge is listed in the Maryland Inventory of Historic Properties as MIHP No. M: 18-47 and is eligible for the National Register of Historic Places. Accelerated bridge construction techniques will be utilized to minimize the disruption to the traveling public and local community. Right-of-way acquisition is not required. Streetlights, crosswalks, sidewalk ramps, bikeways, and other pertinent issues are being considered in the design of the project to ensure pedestrian safety.
