Highway 1 and Lewvan Drive – Regina Functional Planning Study

Introduction

The Government of Saskatchewan wants to hear from you on proposed safety and capacity improvements at the Highway 1 and Lewvan Drive interchange in Regina.

We want you to help guide us with planning for this future project. There is no time frame for possible construction.

Thank you for your participation.

Considerations

The development of the design options considered:

• The existing interchange
• Safety
• Mobility and reliability
• Future traffic volumes
• Locations of utilities
• Available roadway right-of-way
• Construction staging
• Cost
• Existing overpass bridge width

Traffic volumes for the functional planning study included the City of Regina’s 2040 traffic projections and assumed the mixed-use commercial area south of Highway 1 would be fully developed. The existing interchange is shown below.

Options

Five design options are being evaluated based on:

• Safety
• Driver comfort
• Construction cost
• Traffic delays
• Operations and maintenance costs
• Ease of construction
• Stakeholder feedback

Option 1

• A northeast loop ramp without moving the existing off-ramp
• The small loop ramp means lower speeds:
  • 40 km/h on the loop ramp
  • 60 km/h on Lewvan Drive

Benefits:

• Low traffic delays
• Low impact during construction

Drawbacks:

• A low safety score due to the small loop ramp
• Second most expensive option

Option 2

• A ramp merging with the existing westbound on-ramp.
• This option includes traffic signals
• Addition of a northbound lane across the overpass
• 60 km/h speed limit on Lewvan Drive

Benefits:

• Lowest construction cost
• Lowest impact to motorists during construction

Drawbacks:

• Highest traffic delays

Option 3

• A ramp merging with the existing westbound on-ramp
• This option includes traffic signals
• Addition of a northbound lane across the overpass
• 60 km/h speed limit on Lewvan Drive
• An additional lane north of the intersection

Benefits:

• Lower traffic delays than Option 2

Drawbacks:

• Lower safety score than Option 2
• More expensive than Option 2

Option 4A

• A ramp merging with the existing westbound on-ramp
• A roundabout north of the highway
• 50 km/h speed limit on Lewvan Drive

Benefits:

• Low traffic delays
• One of the safest options

Drawbacks:

• High impact during construction

Option 4B

• A ramp merging with the existing westbound on-ramp
• Roundabouts north and south of the highway
• 50 km/h speed limit on Lewvan Drive

Benefits:

• Lowest traffic delays
• One of the safest options

Drawbacks:

• Highest impact during construction
• Most expensive option

Survey closes July 4, 2024

Next Steps

• Gather feedback
• Finalize recommendation
• Public engagement website to present recommended option
• Finalize functional design report.
• Additional design work
• Construction (no timeline)

The Functional Planning Study will be finalized in Summer 2024.
