Southbound Chain-Up Station

Permanent Chain-Up Station Located Near Larkspur 

As part of the I-25 South Gap project, crews have constructed a permanent southbound I-25 chain-up station in the old southbound rest area near Larkspur. During inclement weather, truckers will now be able to use this well-lit chain-up station instead of using the temporary chain-up stations that were created during construction. Please watch for signage for entrance and exit information.

Interstate Closures

Depending on the severity of the weather, CDOT may have to proactively close I-25 for the safety of motorists. If I-25 closes, you can also expect Colorado Highways 83 and 105 to close. Closing I-25 in the construction zone area prevents motorists from being stuck in treacherous weather conditions with no nearby services. Visit for travel information
