Renderings of project - focusing on work on Northbound side. 

Project Scope: This project consists of constructing a new interchange in Saco - Exit 35. This project emerged from the 2019 transportation study that MTA, MaineDOT and the City of Saco participated in which focused on how to address regional traffic issues by improving connections to and from the Turnpike.  This study produced a number of recommendations, including this project. 

The work includes highway, interchange, and toll system construction to create Exit 35 and also includes modifications to the existing Exit 36 Interchange including extending the southbound decel lane.

The new interchange at Mile 35 will include: 
  • Four new ramps - Southbound on and off and Northbound on and off.
  • Two new toll plazas - Southbound plaza will be located on west side of Maine Turnpike with a signalized intersection at Route 112.  Northbound plaza will be on the east side of the Turnpike with a signalized intersection at Route 112. 
  • Construction of a new collector-distributor road - On the Maine Turnpike southbound between Exit 36 and the new Exit 35, the road will be widened to construct a collector-distributor road that will separate Exit 36 on-ramp and Exit 35 off-ramp from the mainline.  It is a two-lane road separate from the three lane mainline. This reduces weaving and merging on the mainline. 
  • Route 112 modifications - In addition to the signalized intersections at the toll plaza ramps, Route 112 will be widened to accommodate turning movements at the new signalized intersections. 
The project includes earthwork, pavement, concrete, signing, overhead sign structures, concrete barrier, guardrail, drainage, stormwater management, electrical work, highway lighting, lightning suppression systems, installation of tolling equipment, administration buildings, canopies, and toll booths and maintenance of traffic.
