No Through Traffic on the Morris Township Road, Detours To Be in Place

Gaston Road, a one-mile street linking Sussex Turnpike and Washington Valley Road in Morris Township, will be closed to through traffic for three months starting March 2, Monday morning, as the County of Morris replaces the aging Gaston Bridge.

The bridge spans a tributary to the Whippany River and is located just north of Jonathan Smith Road, approximately midway along Gaston Road. Its closure will essentially cut the road in half during the bridge replacement work, requiring residents in the area to access their neighborhoods via Washington Valley Road, if they live south of the bridge, or Sussex Turnpike if they live north of the bridge.

Motorists from the south end of Gaston Road can still reach Sussex Turnpike via a detour route that will be marked in the area. From the south end of Gaston Road, motorists will be redirected to Washington Valley Road, Schoolhouse Lane and Mount Pleasant Road, which leads to a point on Sussex Turnpike just a mile west of the north end of Gaston Road.

The current bridge, a concrete slab span consisting of stone masonry abutments and wingwalls, stretching roughly five feet in length, is old and has been repaired multiple times. The masonry structure is deteriorating, and a complete replacement is the most practical and cost effective solution.

The proposed replacement will involve a four-sided, precast structure with stone-faced walls and a picket style railing. Construction is scheduled to start Monday March 2, 2026 and will take three months to complete.

The $641,487 project is being spearheaded by CMS Construction, Inc. of Plainfield, N.J.
