Study Purpose
Study Purpose
The purpose of the study is to identify a technically preferred alternative (TPA) for the underpass replacement and interchange improvements to Waterloo Regional Road 97 (Cedar Creek Road) and Highway 401. The study will generate and evaluate options for interchange improvements, interchange configuration, and structure replacements. Construction of a new commuter parking lot at the interchange is also included.
Study Process
Study Process
The project is being completed following the Class Environmental Assessment (EA) for Provincial Transportation Facilities and Municipal Expressways (2024) as a Group "B" project. Group “B” projects are considered approved, subject to compliance with the Class EA. The EA process involves the collection and integration of input from various engineering and scientific studies, as well as public, Indigenous, and agency consultation.
A Transportation Environmental Study Report (TESR) will be prepared for a 30-day public review period towards the end of the study. The TESR will document the consultation, describe the evaluation and selection of the TPA, provide details on the Preliminary Design of the TPA and outline environmental mitigation measures and provisions that have been incorporated into the design.

Project Construction and Preliminary Detour Routes
Project Construction and Preliminary Detour Routes
There will be intermittent Highway 401 lane and ramp closures, as well as more substantial closures of Cedar Creek Road and Industrial Road to facilitate construction. Preliminary detour routes have been identified to accommodate Cedar Creek Road closures.
Please refer to the following handout for information on currently proposed detour routes. The final construction schedule and construction staging arrangement will be decided by the future Design-Build Team: Proposed Detour Route Notice
