The $20 million, 3.2-kilometre Bramalea Road widening project from Sandalwood Parkway to Mayfield Road for the City of Brampton involved road reconstruction and widening from 2 lanes to 4/5 lanes. This project, which was built in three phases, demonstrates CFA’s ability to successfully deliver a complex project that incorporates multi-disciplined infrastructure, traffic staging, extensive utility relocation and coordination, public consultation with residents and businesses, and effective agency liaison to secure approvals and meet requirements that evolved over the duration of the project.
The sidewalk was designed as a connecting link between two high traffic generators, Sesquicentennial Park and the Smartcentres shopping plaza. The two-sided sidewalk was supplemented with bike trails adjacent to the kill-strip. The design included enhanced AODA features for each of the road crossings.
Key features:
- A new 400 mm diameter concrete-encased ductile iron watermain
- Replacement of an aging 150 mm diameter asbestos concrete sanitary sewer forcemain with a 450 mm diameter gravity sewer at a depth of 8 m under the road
Some of the challenges encountered in the project included:
- Extensive redevelopment in the project area calling for significant coordination with several other consultants and construction projects
- Extensive relocation of utilities (including 5 km of hydro poles, Bell lines and gas lines) resulting in extensive coordination, design changes, and review and approval of utility-owner designs
- During the multi-year construction, Redside dace became a provincially listed then a federally listed endangered species, resulting in additional study as well as prolonged coordination and permitting with the TRCA and ministries, and significant redesign of one of the three water crossings.
Innovation:
- Traffic-operation improvements
- Improved road safety through improved sight lines, the elimination of road flooding, and roadside design changes
- Stormwater quality improvements
- Improved Redside dace habitat
- Reference to 2013 CFA Project Bramalea Road Forcemain from Inspire Boulevard to a 375 mm Gravity Sewer completed with the design of twin 75 mm forcemains that connected a shopping plaza to an existing 375 mm gravity sewer. The 350 m sections were installed through HDD and crossed over a 3.6 m span, open-foot concrete culvert. The forcemains were installed within the roadway to Peel Region standards, in a TRCA-regulated area.
