MassDOT to Motorists: Plan Ahead for Weekend Overnight Callahan Tunnel Closure in Boston
Closure on Friday June 20th and Saturday June 21st from 12 AM to 6 AM
 BOSTON- June 17, 2014—This coming Friday, June 20 and Saturday, June 21, the Callahan Tunnel will be closed overnight from the hours of 12am until 6am.   This is the first overnight closure for the Callahan Rehabilitation Project since it was reopened to traffic on March 10, 2014.
The detour in place for Friday and Saturday night will be as follows:
Starting along I-93 SB, traffic will be directed to Exit 23 Purchase Street.  At the end of the ramp, traffic will be detoured to the left over the Moakley Bridge.  Following that, traffic will turn right onto Boston Warf Road and follow straight across Congress Street to West Service Road returning to the on ramp to I-90 EB. 
Traffic from Haymarket will be allowed to enter 93 SB only and will be detoured to use Exit 23 Purchase Street upon entering tunnels and follow the detours as noted above.
The complete closure will allow for the paving of the entrance and exit of the Callahan Tunnel. 
MassDOT encourages drivers to avoid the area and seek alternate routes to minimize delays.  Those traveling through the area should expect delays and should reduce speed and use caution while traveling along the detour routes.
