February 24, 2021 - Central/Eastern Colorado - The overnight closure will allow crews to finalize the newly extended and widened on-ramp to northbound I-25

DENVER COUNTY – The Colorado Department of Transportation and contractor ABCO Contracting will close southbound Interstate 225 at the Tamarac St/DTC Blvd Exit 2A during overnight hours on Tuesday, March 2, 9 p.m. to 5 a.m. (rescheduled from Wednesday night, February 24 and then from Sunday night, Feb. 28 due to weather).The closure is necessary so crews can remove temporary barrier and restripe the newly widened and extended two-lane on-ramp to northbound I-25 from mainline southbound I-225. Detour signage will be in place during the closure to safely direct motorists to alternate routes. Once reopened, no more restrictions will be in place. This widening was part of a three phase traffic flow and ramp safety improvement project at two key locations on southbound I-225.

Travel Impacts

  • Full interstate closure – Southbound I-225 at Tamarac St/DTC Blvd (Exit 2A) will be closed 9 p.m. Tuesday, March 2 until  5 a.m. Wednesday, March 3. Motorists should prepare for 10 minute delays as they will be detoured around the closure, adding two miles. 

  • Advanced warning and detour signage will be in place to alert drivers to the overnight closures.

Project Background

This three phase project was designed to improve capacity and make safety upgrades at two key interchanges on southbound I-225: at the South Parker Road exit and at the junction of southbound I-225 at the on ramp to northbound I-25. Phase I consisted of adding an auxiliary lane on southbound I-225 approaching the Parker Road off-ramp and is complete. Phase II entailed widening and extending the off ramp to South Parker Road at Exit 4, and Phase III encompassed extending and widening the on ramp to northbound I-25 from mainline southbound I-225 at Tamarac Street/DTC Blvd. All phases of this project will be complete late February, depending on the weather.
