The Mashpee Chamber received a more detailed update on the meeting held regarding the upcoming bridge work:

Dear Chamber Member,
This morning I attended a meeting hosted by the RTA and presented by the Army Corps of Engineers regarding the upcoming work and lane closures on the Sagamore and Bourne Bridges.

The Sagamore bridge will be reduced to two 12 foot lanes starting April 2 through May 25th.  Work is scheduled to replace expansion joints and seams that require attention.  The bridge will be divided into three lanes, one area for work and two areas for travel.  The work and travel lanes will change through three phases of work each to last about 2.5 weeks.

The work crews will work 2 eight hours shifts seven days a week to complete this work.

The Bourne Bridge will have similar repairs made starting September 5 through November 26 with a weekend off for Columbus Day.  The bridge is somewhat larger so there are more seams to be replaced plus some steel and concrete repairs are needed as well.  There will be a similar division of lanes and work schedule as noted above for the Sagamore Bridge

There were about 100 people in attendance included the Canal Region Chamber of Commerce and the Cape Cod Chamber of Commerce, representatives from Cape Cod 5 and other local businesses, political representatives, their representatives and Mass DOT representatives; a full room.

The meeting was emotional and passionate when it came time for audience remarks.  The audience made the following points.
1.  We need new bridges pressing for a date to conclude this need.
2.  September is still high season and the work on the Bourne Bridge should be delayed.
3.  The contractor should work three shifts.
4.  Business needs off Cape labor to operate and they need a way to get here in an timely manner.
5.  The group criticized the Corp for lackluster ideas dealing with traffic.

Other ideas were offered to mitigate congestion.
1.  Single direction flow for all traffic during peak times
2.  Use of the railroad bridge
3.  Closing exit 1

Regarding communication, the Corps suggested that they will use current communication tools like “Bridge Alert” emails to share information and alerts.  If you would like more information or if you would like to sign up for bridge alert emails, please follow this link.  Bridge Alerts
