  1. No left turns on the bridge from northbound I-25 to westbound County Line/Palmer Divide Road
  2. No left turns on the bridge from southbound I-25 to eastbound County Line/Palmer Divide Road

These restrictions are expected to remain in effect throughout bridge construction for the safety of crews and the traveling public. Please use CO 105 (exit 161). Once the bridge opens, watch for lower speeds and narrower lanes.
