Drivers on Route 609 in Hamilton will have to follow detours for much of the year while state contractors reconstruct the bridge over Route 130.

In a Monday press release, the New Jersey Department of Transportation announced the bridge will be closed in both directions starting March 22. Contractors might also have to close one lane of 130 during off-peak hours as part of the construction. The project is expected to finish by fall this year, according to the release.

Northbound drivers on 609 can use Main Street to South Broad Street and then Route 156 to bypass the bridge. Southbound drivers can take the reverse route: 156 to South Broad Street to Main Street.

Route 130 northbound drivers trying to take 609 can take South Broad Street to Main Street, as the exit to 609 will be closed during the construction.

Contractors will replace the bridge’ structurally deficient superstructure, make some substructure repairs and resurface the road at either end of the bridge as part of the $1.78 million federally funded project.

The timing of the work and the entire project is subject to weather and “other factors” according to the release.
