Benefits

Trade-offs

• Reconfigured interchange at Blackfoot Trail reduces weaving around Deerfoot Trail and Glenmore Trail.
• Reconfigured interchange at Glenmore Trail provides for all movements and removes the use of Heritage Meadows Road to perform northbound to westbound movement.
• Reduces congestion on Deerfoot Trail from northbound Heritage Meadows Road off-ramp.

• Potential impacts to commercial/industrial properties.
• New design accommodates all the movements at the Glenmore Trail and Deerfoot Trail interchange and warrants removal of the right-in / right-out access on Glenmore Trail in both directions.
• High costs due to constructing new ramps.

Benefits of concept one

Trade-offs of concept one

• Reduces weaving along Deerfoot Trail by adding a collector distributor (CD) lane in each direction between Southland Drive S.E. and Anderson Road / Bow Bottom Trail S.E. This separates the highway through movements from the interchange movements at the entrance and exit ramps.
• Provides more capacity with an additional lane in each direction across the Bow River and with the CD lanes north of Southland Drive.
• East / west traffic continues to use the Deerfoot Trail corridor via the CD lanes north of Anderson Road/ Bow Bottom Trail S.E. interchange while the core lanes are primarily reserved for north/south traffic.
• Improves the diverging operations along northbound Deerfoot Trail by enlarging the loop ramp for Anderson Road / Bow Bottom Trail S.E.

• Potential impacts to properties including Sue Higgins Park, Maple Ridge Golf Course and private property.
• Moderate costs due to constructing new overpasses for basket weave structures and separating the exit and entrance ramps between Anderson Road / Bow Bottom Trail S.E. and Southland Drive S.E. interchanges.

Benefits of concept two

Trade-offs of concept two

• Reduces weaving along Deerfoot Trail by adding a collector distributor (CD) lane between Southland Drive S.E. and Anderson Road/Bow Bottom Trail S.E., separating the highway through movements from the interchange movements at the entrance and exit ramps.
• Provides additional highway capacity, including across the Bow River, with the two CD lanes in each direction starting at Barlow Trail.
• Provides improved traffic operations along Deerfoot Trail as the CD lanes accommodate east/west local trips separately from the north/south trips that would primarily use the core travel lanes.
• Improves the diverging operations along northbound Deerfoot Trail by enlarging the loop ramp for Anderson Road / Bow Bottom Trail S.E.
• Provides additional distance northbound to change lanes by reconfiguring the ramps at Southland Drive.
• Provides easier connection between Blackfoot Trail and Southland Drive by reconfiguring intersection.

• Potential impacts to properties including Sue Higgins Park and private property.
• Moderate to high costs, primarily associated with the new structures across the Bow River and through the Anderson Road / Bow Bottom Trail S.E. interchange to accommodate the northbound and southbound CD lanes.

Benefits of concept three

Trade-offs of concept three

• Reduces weaving along Deerfoot Trail by adding collector distributor (CD) lanes in each direction between Southland Drive S.E. and Anderson Road / Bow Bottom Trail S.E., separating the highway through movements from the interchange movements at the entrance and exit ramps.
• Provides additional highway capacity, including across the Bow River with the two CD lanes in each direction starting at Barlow Trail.
• Provides improved traffic operations along Deerfoot Trail as the CD lanes accommodate east/west local trips separately from the north/south trips that would primarily travel in the core lanes.
• Provides direct access between Blackfoot Trail and Deerfoot Trail.
• Increases capacity and improves traffic operations by replacing existing loop ramp with directional ramp at Deerfoot Trail and Anderson Road.

• Potential impacts to properties including Sue Higgins Park, Maple Ridge Golf Course and private property.
• High costs due to constructing new access between Deerfoot Trail and Blackfoot Trail, new bridges across the Bow River to accommodate the CD lanes and reconfiguring the Anderson Road / Bow Bottom Trail S.E. interchange.
