Vehicles cross the Piscataqua River Bridge into Maine in this 2015 BDN file photo.

Bridge work is scheduled on the Interstate 95 Piscataqua River Bridge that connects New Hampshire and Maine.

The work is scheduled for 10 a.m. Monday, weather permitting, on the southbound side in Portsmouth, New Hampshire, for several hours to install new median signs. It will require a temporary lane closure.

This work is part of the three-year renovation project on the bridge, which is a joint project with the Maine Department of Transportation.
