The Highway 407 East (407E) P2 project is an extension of the original 108 km-long 407 Express Toll Route in the province of Ontario, the first electronic toll highway in the world. P2 (Phase 2) is a Design-Build-Finance-Maintain (DBFM) project which links major interchanges and eases congestion of the highly trafficked 400-series highways in the Greater Toronto Area.
The current extension of Highway 407 is approximately 22 kilometres in length, beginning at Harmony Road in Oshawa to Highway 35/115 in Clarington, and a 10-kilometre north-south connection of Highway 401 to Highway 407 by way of Highway 418.
Since 2016, Reinforced Earth Company Ltd. (RECo Canada) has continued to contribute their experience, knowledge and expertise in the design and supply of MSE walls in conjunction with all involved parties in order to deliver a successful major project.
The 407E P2 is a public-private partnership (P3) project and the scope of work is approximately 22,000 sq m distributed throughout 36 structures which consists of wing walls, false abutments and other structures including a wall considered to be under submerged conditions. The Reinforced Earth® techniques that continue to be utilized within this project are the TerraClass® and TerraTrel® systems which implement galvanized steel soil reinforcing strips.
The largest wall with respect to area is 3,000 sq m and the tallest in terms of height is 11m. Due to the tight construction schedule and in order to achieve the many milestones of the project, it was deemed necessary to accelerate the fabrication process of the precast panels on two separate occasions.
By the end of 2019, the whole Highway 407 extension and Highway 418 will be open to traffic.
