PTH 75 is a major international shipping route, connecting Manitoba and Winnipeg to theEmerson Port of Entry and the United States interstate system.

Flooding of the Red River has closed PTH 75 in the past causing inconvenience, stress andcosts to the people and the businesses of the Red River Valley and beyond.

Why is the province undertaking the study?

Since 2005, the province has completed over $125 millionin upgrades to PTH 75, with additional work planned.

The province hasconsidered optionsto determine the bestapproach to raising PTH75 and a number of otherroads.

The hydraulic impactstudy will identify ways tocomplete the upgrades withlittle or no changes to theextentthatoodingalready

occurs.

Considerations for upgradesThe province last met with stakeholders in Morris in May of 2010. Based on the feedback from thismeeting, Manitoba Infrastructure and Transportation developed the parameters for the hydraulic impactstudy.DuetooodingandoodrecoveryeffortsacrossManitobain2011,thestartofthestudywas

delayed until this year.

The study will consider the following:

RaisingPTH75willprovideaccessupto2009ood

levels. This will be similar to the level of protectiondone for I-29 in the United States and allow the Portof Entry at Emerson to remain open.

Other major roadways in the area may also be raised

to2009oodlevelsincluding: PR 201 at the Rivire Aux Marais, PR 422 at the Little Morris River, PTH 23 west of the Town of Morris, and PTH 23 east of the Marsh River crossing.

The study will consider relocation of the Morris River

north of Morris with a new bridge in that location.Raising the bridge over the Morris River to protectagainst2009oodlevelsatthecurrentlocationis

impractical.

Proposed extensions to the Morris dike will also beconsidered in the study.

The study area for the

hydraulic impact study

will be from Winnipeg to

Grand Forks. There will be

a focus on areas where

upgrades are proposed.

Study Process

There are several steps required to complete the study.

Collectionandreviewofexistingdata(waterlevels,ows,oodedareas,roadandrailwayelevations,

culvert sizes), Obtain survey information, and

Gatherlocaloodknowledge.

Develop alternatives to possibly raise the following roadways: PTH 75 from Aubigny to St. Jean Baptiste, PR 201 at Rivire aux Marais, PR 422 at Morris River, PTH 23 west of Morris, and PTH 23 at Marsh River.

Opportunities to participate

There will be several opportunities for people

to provide inputs to the study.

Round1:Todayistherstopportunityforpeople to provide the study team with local

study team also wants to understand how

people would like to be engaged as the

study proceeds.

Round2: The second round of consultation

will be an opportunity to review initial results

from the modelling, including potential

strategies to adjust proposed upgrades to
