Tech to monitor bridge as breakdown lanes open to traffic

Maine and New Hampshire transportation departments are preparing to roll out the tech to keep travel moving during peak travel periods on the Interstate 95 bridge that connects the two states.

Workers will be finishing most of an overhaul of the Piscataqua River bridge by this fall and the technology upgrades begin after the work is completed, said Charles Blackman, intelligent transportation systems engineer for the New Hampshire Department of Transportation.

Additional cameras and sensors will be installed to detect traffic flow and slowdowns, and that information will be more important because engineers plan to open the breakdown lanes for travel during congested periods, Blackman said. The move would boost the traffic volume in each direction by more than 1,000 vehicles per hour.
