Major impacts to I-25 near 136th Avenue this weekend for paving work, delays expected

November 15, 2019

THORNTON, CO — As major work nears completion on the North Interstate 25 Express Lanes: 120th Avenue to Northwest Parkway/E-470 project, crews will require double lane and ramp closures in both directions of I-25 at 136th Avenue to perform final paving on the bridge over Big Dry Creek. Delays are expected.

Traffic Impacts

5 a.m. to 10:30 a.m. on Saturday, Nov. 16 – Double right lane closure on northbound I-25 between 128th and 136th avenues and full closure of the northbound I-25 off-ramp to 136th Avenue. One lane will remain open on northbound I-25. From 10:30 a.m. to 12 p.m. it will turn into a single right lane closure. Motorists may stay the course on northbound I-25 or use Washington Street to the east of the highway as an alternate route.

2 p.m. to 4 p.m. on Saturday, Nov. 16 – Double right lane closure on southbound I-25 between 144th and 136th avenues and full closure of the 136th Avenue on-ramp to southbound I-25. One lane will remain open on southbound I-25. From 4 p.m. to 7 p.m. it will turn into a single right lane closure. Motorists may stay the course on southbound I-25 or use Huron Street to the west of the highway as an alternate route.

This work is critical to complete and requires warmer, daytime temperatures. All work is weather dependent. If paving is unable to be complete on Saturday, Nov. 16, due to weather, this schedule will shift to Sunday, Nov. 17.

This work marks the final paving operation of the North I-25 Express Lanes: 120th Avenue to Northwest Parkway/E-470 project. Daily and nightly lane closures will continue as crews install final pavement markings, center median lighting and tolling infrastructure.

Additional lane closures for equipment installation include:

  • 8 a.m. to 6 p.m. on Saturday, Nov. 16- Single left lane closure on northbound I-25 between 120th and 128th Avenues.
  • 8 a.m. to 6 p.m. on Sunday, Nov. 17- Single left lane closure on southbound I-25 between 120th and 128th Avenues.

Project Benefits

  • Add capacity with one Express Lane in each direction.
  • Provide travelers with the choice of taking the general-purpose lanes for free or driving the Express Lanes for a faster trip in exchange for a variable toll - the Express Lanes will be free to vehicles with three or more people.
  • Build an auxiliary lane along northbound I-25 connecting the 136th Avenue on-ramp to the 144th Avenue off-ramp, helping drivers merge more comfortably between the two interchanges.
  • Resurface the roadway which will improve driving conditions.
  • Address necessary drainage and utility improvements along the corridor.
