Metro-North begins work on two Mount Vernon bridges

Metropolitan Transportation Authority's Metro-North Railroad is refurbishing two bridges in Mount Vernon, N.Y., this summer, one that carries cars over train tracks and one that carries train tracks over cars.

Metro-North begins work on two Mount Vernon bridges

The Oak Street Bridge that carries Harlem Line trains on three tracks over Oak Street on the west side of the city is being painted and the two-lane Fourteenth Avenue Bridge that carries cars over the New Haven Line in the east side of the city is getting priority structural repairs.

Portions of the Oak Street Bridge that have rusted due to water leakage will be sanded and painted. The contractor, East Coast Painting, also will paint the fascia girders and an anti-graffiti coating will be applied. The-$145,000 job is set to begin in mid-August and take two to three weeks to complete. The work will require one lane closure at a time while the girders are painted and a roadway flagman will be used.

The Fourteenth Avenue Bridge, which was built in 1894 and straddles four electrified tracks, is 92-feet-long, single span, steel truss with steel floor beams and an asphalt-covered, timber deck slab. The span is supported by masonry abutments. The sidewalks, one of asphalt and the other bare timber, are supported by cantilevered steel brackets.

Metro-North's Structures Department will perform almost $350,000 in priority repairs to this bridge, including stabilizing the superstructure, which is scheduled to begin August 1 and be completed by the end of September.
