Frontage Roads

East and West Frontage Road Drainage Block Closures Complete

Drainage-related work on the frontage roads is complete. We appreciate your patience!

During this work, crews:

  • Replaced 11 total drainage crossings on the West Frontage Road
  • Replaced 23 total drainage crossings on the East Frontage Road
  • Replaced 20,450 linear feet of drainage – that would be like stacking the Empire State Building on top of itself 16 times!
  • Maintained access through the closures to emergency services
  • Successfully used a temporary flagging signal to reduce 24-hour flagging operations on the West Frontage Road
  • Installed guardrail along the frontage roads in safety-critical areas
  • Replaced three retaining walls to allow water from I-25 to flow to designated areas along the frontage roads

Additional Frontage Road Work

Additional closures on the frontage roads will be scheduled for crews to install deer guards. Flagging operations on both the East and West Frontage Roads will continue, Monday through Friday, from 7 a.m. to 5 p.m. Please continue to give yourself extra time if you plan to travel on the frontage roads.

Safety First

  • The speed limit along frontage roads has been reduced to 45 mph. During flagging operations, it will be 40 mph.
  • Please pay attention.
  • If you are not local traffic, please stay the course on I-25
  • Remember: both frontage roads are striped with double-yellow lines, so passing is legally prohibited.
