MassDOT reports it's turning on a network of eight signs on roads leading to the Chelsea Street Bridge that will alert motorists when the bridge is unpassable because a boat is passing underneath or it's otherwise stuck and unable to carry traffic.
The total cost for developing and installing the new notification system for the Chelsea Street Bridge was approximately $234,000. The bridge handles a daily volume of approximately 37,000 vehicles and is raised an average of 5 times per day to allow for the passage of incoming vessels.
The Chelsea Street Bridge was constructed in 2012 and carries traffic on Chelsea Street over the Chelsea Creek. The bridge is approximately 450 feet in length and when raised has a vertical clearance of approximately 175 feet.
