CDOT Hosting I-25 South Gap Project Telephone Town Hall

Sept. 5, 2018 -

Telephone Town Hall Details

Starting at 6:15 p.m., an automated system will call residents at random to participate. Those who don't receive calls but wish to join can call toll free, 1-877-229-8493, and enter passcode 117409.


DENVER—At 6:15 Thursday, Sept. 6, travelers can learn more about the 18-mile I-25 South Gap project that started this week by joining a telephone town hall.

CDOT is hosting the telephone town hall so drivers can learn more about the project and expected traffic impacts over the next three years of construction. Most importantly, attendees can also ask questions that will either be answered on the call or through follow up.

The I-25 South Gap project will:

  • Add one lane in each direction between Monument and Castle Rock. The new lane will operate as an Express Lane, so motorists will always have the choice of taking the two general-purpose lanes for free or taking the Express Lane for a reliable trip in exchange for a toll.
  • Widen shoulders to allow room for enforcement zones, maintenance and detours around incidents.
  • Rehabilitate structures and pavement, including the replacement of four bridges.
  • Build four wildlife underpasses and expand the existing one at Plum Creek.
  • Improve lighting, signage, fencing and other features.

Travel Impacts

Drivers can expect two lanes of traffic to remain open during the day. From 8 p.m. to 5:30 a.m., crews will close lanes for safety.

Most initial traffic impacts will be focused in the northern section of the project, between Plum Creek Parkway and Sky View Lane. Still, motorists will see some construction activity corridor-wide where crews are relocating the fiber optic lines east of I-25.

Work in additional areas along the corridor will begin in phases. By summer 2019, the entire 18-mile stretch will be experiencing active construction. Substantial construction completion is planned for late 2021, with tolling to begin in 2022.
