Frequently Asked Questions

What is PTH 100?

PTH 100, the South Perimeter Highway, is part of the ring road originally constructed in the 1950s and 1960s as a bypass route around the City of Winnipeg, and, together with PTH 101, is known as the Perimeter Highway. PTH 100 extends from Portage Avenue at the west to Fermor Avenue at the east along the south side of the City of Winnipeg and is accessed via stop-controlled and signalized at-grade intersections and interchanges.

Why is PTH 100 being studied?

Since the original construction of PTH 100, residential, commercial, and industrial growth in Winnipeg and its adjacent municipalities has expanded towards PTH 100. This growth has resulted in an increase in urban traffic demand on PTH 100, and a decline in the percentage of traffic using PTH 100 as a bypass. Traffic volumes on PTH 100 have increased by 100% since the South Perimeter was last studied in 1988. As a result, safety, operational, and capacity deficiencies have also significantly increased.

What is the South Perimeter Highway Design Study?

This is a preliminary design study to plan for the reconstruction of the South Perimeter Highway (PTH 100), to a freeway standard with provision for future expansion to six lanes. It will locate and develop designs for all required interchanges and crossing structures (road, rail and waterways) to a preliminary level. The result will be a plan to upgrade PTH 100 to a modern freeway thoroughfare, where highway access is provided by service roads, ramps or loops, and interchanges with overpass structures.

An element of this project includes the preliminary design for a bypass of St. Norbert. Since an interchange will be required on the South Perimeter to accommodate a future bypass, the preliminary design of its alignment is being included in this study to fix the PTH 100 interchange configuration and location.

South Perimeter Highway Design Study Area

What is a preliminary design?

A preliminary design is an early phase of the design process in which the road right-of-way and roadway design (i.e., lane width, intersections, etc.) are established. Structure requirements are also part of the preliminary design to fix location, type and dimensions. Such designs are informed by technical studies which help identify projected travel patterns, demand for roadways, geotechnical conditions, hydraulic conditions, and environmental requirements. Public input and feedback are considered throughout the process.

What is the purpose of the study?

The study will guide more detailed design work and reconstructions on PTH 100 in the future, preserve the necessary land for the proposed improvements, recommend grade separated replacements or closures for existing at-grade access points onto the South Perimeter Highway, and support local area development and land-use planning.

Will my property be impacted?

In order to design PTH 100 to a freeway standard, there will be some property impacts. MI will meet with impacted property owners throughout the study to discuss any potential property impacts.

Will my access be impacted?

In order to design PTH 100 to a freeway standard, there will be changes to some accesses. MI will meet with impacted property owners throughout the study to discuss any potential access impacts.

How long will the study take?

The study is estimated to take two years to complete.

Who is working on the study?

WSP Canada Group Limited (WSP), an engineering and planning consulting company, has been retained by the Province of Manitoba to complete the study.

How can I stay involved in the study?

Throughout the project, there will be many opportunities for municipalities and interested individuals to learn more about the study and provide input towards the design recommendations. We will be visiting communities within the study area to share information, answer questions and gather important feedback from you. Event dates will be posted on the project website and opportunities for productive public engagement sessions will be announced soon.
