Demolition, site work, paving and new construction of a bridge / tunnel in Silver Spring, Maryland. Design plans call for the demolition of a bridge / tunnel; for the construction of a bridge / tunnel; for site work for a bridge / tunnel; and for paving for a bridge / tunnel.

This project provides for the replacement of the existing Dennis Avenue Bridge M-0194 over a tributary to Sligo Creek. The existing bridge, built in 1961, is a single 30-foot span structure composed of prestressed concrete voided slab beams carrying a 24-foot roadway, two six-foot shoulders, and two 4'-8" sidewalks. The proposed replacement bridge will be a 80-foot overall span three-cell precast concrete arch culvert carrying a 22-foot roadway, two five-foot bicycle compatible shoulders, two two-foot striped buffers, a 13-foot shared-use path on the north side and a seven-foot sidewalk on the south side, for a total clear bridge width of 56 feet. The project includes utility relocations and approach roadway work at each end of the bridge as necessary to tie into the existing roadway and sidewalks. The bridge will be closed to traffic during construction. Accelerated bridge construction techniques will be utilized to minimize the disruption to the traveling public and local community. This project is included in the county's fy 2025-2030 Capital Improvement Program. As of January 31, 2024, further details regarding design and construction timelines have not been identified. *Project information has been obtained through a public capital improvement plan (CIP).
