This work will facilitate the addition of a third westbound lane on Karcher Road to accommodate higher traffic volumes. Other improvements for this project include:

• Adding a free-running right hand turn at the westbound off-ramp
• Paving a third westbound lane on Karcher Road from the westbound off-ramp to Sundance Road
• Reinforcing the Indian Creek Bridge to support the new lane
• Updating signal equipment and adding a pedestrian flashing beacon at the eastbound on-ramp
• Building a mixed-use path on the north side of Karcher Road

These improvements will increase safety and traffic flow at the interchange. Construction is expected to be completed in fall 2025.
