THE
PTH 1 and PTH 1AWest Interchange Study
PTH 1 and PTH 1A West Interchange Study
2
WELCOME & PURPOSE
The intent of today’s open house is to:
• Provide information on the purpose and scope of the PTH 1 and PTH 1A Interchange Study;
• Present the interchange alternatives, as well as the advantages and disadvantages associated with each alternative; and
• Offer the public an opportunity to review the interchange alternatives, provide feedback, and ask questions of the project team.
Completing a comment sheet here today or online at: https://www.gov.mb.ca/mit/wms/structures/design.html
Members of the project team are here to discuss the study and answer any questions you may have. Look for a person wearing a WSP or Manitoba Infrastructure nametag.

PTH 1 and PTH 1A West Interchange Study
3
The existing overpass structure (bridge) at PTH 1 and
PTH 1A was constructed in 1968 as part of the Trans-Canada
Highway (PTH 1) by-pass around Portage la Prairie (Portage).
The bridge is located west of Portage and was designed to
convey 3 lanes of PTH 1A traffic (2 northbound lanes into
Portage and 1 southbound lane out of Portage) over 4 lanes
of PTH 1 traffic (2 eastbound lanes and 2 westbound lanes).
Over the years, the bridge has been damaged by several
vehicle impacts, and many bridge elements are exhibiting
significant deterioration. As a result, the bridge is
currently restricted to a single lane.
Manitoba Infrastructure (MI) has determined that it is
not cost effective to rehabilitate the bridge and a new
structure is required at this location. As part of this
study, MI is also looking to improve the interchange.

1. Replace the bridge;
2. Improve traffic operations and safety by bringing the interchange to current design standards; and
3. Accommodate the access needs of the public and established industry in Portage.
Manitoba Infrastructure has engaged WSP (an engineering and planning service provider) to complete a functional design study for the future reconstruction of all roadways and the bridge structure within the PTH 1 and PTH 1A interchange to:
A functional design study is an early phase of the design process in which the road and bridge designs are established based on projected travel patterns, design standards, site conditions, environmental regulations, user demands, and project constraints.

SCOPE
Note: Due to funding constraints Manitoba Infrastructure may need to complete this project in phases with the initial phase including the replacement of the overpass.

The public engagement process for the study involves local governments, landowners, business owners, other stakeholders, and the public.
The objectives of the public engagement process are to convey clear information about the project, including its scope and timing, while also gathering input regarding the proposed interchange alternatives and preferred interchange alternative.
Public engagement techniques will include:
- Group stakeholder meetings;
- Two public open houses;
- Project webpage; and
- Online survey.
PUBLIC ENGAGEMENT PROCESS

The public engagement process has been divided into three phases:
1 2 3Phase 1:
Introduce the project and gather initial feedback.
Phase 2:
Present two interchange alternatives and gather feedback.
Phase 3:
Present the preferred interchange alternative.

Due to safety concerns, the intersection at PTH 1 and Road 40 W will be closed in both of the proposed interchange alternatives.
This will impact access to and from the lands to the south of the interchange.
Alternative access and routes will be provided for both of the proposed designs, as illustrated on the Interchange Alternative #1 and #2 drawings. The intersection will not be permanently closed until alternate access is provided via the interchange.
