Project Description
State Project No. 300-102
Abutment Slope Stabilization of Metro-North Railroad
Bridge No. 01302R over
Old Stamford Road (Rte. 106), New Canaan
Bridge No. 01302R carries the New Canaan Branch of Metro-North Railroad over Old Stamford Road (Rte. 106), New Canaan.
This open deck bridge was constructed in 1906 and consists of a single 55’-0” long riveted built-up girder-floorbeam-stringer span. The superstructure is supported by two abutments, stone masonry at the south and cast-in-place concrete at the north. Both abutments are founded on ledge with a concrete protective coating. The bridge is currently posted for a minimum vertical clearance of 11’-3” with a field measured minimum vertical clearance of 11’-6”.
The structure carries a single track of the Metro-North New Canaan Branch. Recent bridge inspections have revealed weathering at the exposed ledge under the southwest wingwall. This is causing the rock to fracture and fall away undermining the base of the wingwall. The other wingwalls are also showing signs of deterioration with stone ballast falling into the roadway below because they are too short. Improving the substructure’s integrity through rehabilitation of all wingwalls is the purpose of this project.
Proposed Rehabilitation
The project involves slope stabilization at all four wingwalls with no road improvements. This proposed rehabilitation will stabilize the exposed ledge and repair or replace the wingwalls to hold back railroad ballast.
