Thank you for reporting this issue. The Department of Public Works will address this issue. An update will follow.

The city of Northampton has a study they did with a similar bridge issue: http://www.pvpc.org/resources/transport/rte9_overp_final.pdf

Write a comment...There are more than a dozen signs warning drivers of the reduced height of the underpass covering all approaches to the bridge; the northbound approach from Main St. has four signs posting the height of the bridge. The city has made met its obligation in posting notice of this hazard to motorists. The city is also looking into funding for a more advanced warning system similar to what Northampton's done for their low bridge issue.
