Here's the latest from Mike Keegan of the Army Corps of Engineers:
Just a reminder that starting at 7:00 am on Saturday 28 September 2013 we will start implementing the Brookline Avenue detour. This will turn Brookline Avenue into a one way roadway inbound between the Riverway and Park Drive.
Traffic coming down Brookline Avenue or Boylston Street outbound that want to continue down Brookline Avenue to the medical center will need to travel around the rotary between Brookline Avenue, the Riverway and along Fenway. New traffic signals will be installed to ease the congestion that occurs when traffic traveling down Park Drive from Brookline tries to merge with traffic exiting the Riverway from Brookline. (A figure showing the new traffic pattern for this period is attached to this email).
A new pedestrian walkway has been constructed around the former Sears parking lot for pedestrian travel through the project area.
These changes are being made so that the installation of a culvert under Brookline Avenue can continue. There will be variable message boards that will assist drivers on how they should travel to be able to continue down Brookline Avenue outbound to the Longwood Medical Area. Police details will also be used to assist drivers during the initial stages of this traffic pattern change.
I have also attached a news release regarding this traffic change that was release by my office last Friday. If you have questions please feel free to contact me at the contact info below or email me at MuddyRiver@usace.army.mil
