[ARCHIVED] **MAJOR TRAFFIC ALERT** Next Phase of I-295 Exit 7 Lane Closures Begins May 19th

The final phase of the City of Portland’s I-295 Exit 7 (Franklin St) closures will begin Thursday, May 19th.  All Exit 7 ramps, northbound and southbound will experience Single Lane closures during the daytime over the next 5 weeks and complete closure for overnight paving operations tentatively the week of June 20th.  During the overnight paving operation, the intersection of Marginal Way and Franklin Street will be closed in all directions except for allowance of a right turn from Marginal Way onto Franklin Street heading East which is the Metro bus route.  Access to Marginal Way will be available through local streets.  

Variable message boards and a traffic control plan rerouting motorists will be implemented.  Motorist are encouraged to use Congress Street or Cumberland Avenue as detour routes around the project area.  Motorists should make plans to seek alternate routes during this time. 

These closures are part of the City’s Back Cove South Storage Facility Project which installed utilities within the intersection of Marginal Way and Franklin Street to the new storage tanks under the Preble Street playing fields.  There is some final drainage, curbing, guardrail and pavement that needs to be installed.

The project is one of the City’s latest sewer separation projects to prevent combined sewer overflows into Back Cove. The work to reduce overflows is part of the City’s agreement with the U.S. EPA to reduce and eliminate the flow of combined waste being discharged. A combined sewer system transports wastewater from home, industries, and businesses, as well as storm water collected from streets, parking lots, roofs, and yards to the East End Wastewater Treatment Plant. A combined sewer overflow occurs when the combined sewer capacity is overwhelmed during heavy rain events and a mix of sewer and storm water is discharged into Back Cove. 

The Department of Public Works has been coordinating with the prime contractor, Sargent Corporation, and the Maine Department of Transportation as part of a traffic control plan to minimize the impacts to the traveling public.
