Traffic Impacts

For the week of Sept. 19

General Overview

Updated Lane Closure Hours: As project progress continues, almost all our night work is either paving, moving barrier to pave or striping new pavement. Paving and painting is highly dependent on temperatures. As our paving season comes to a close, we want to squeeze out every second. Starting Monday, Sept. 20, our new routine single lane closure schedule on both northbound and southbound I-25 will be:

  • Monday through Thursday, 7 p.m. to 5 a.m.
  • Friday and Sunday, 8 p.m. to 5 a.m.

Project Offices in Castle Rock

A temporary construction office for CDOT and its contractor partner, Kraemer North America, is located near the intersection of Crystal Valley Parkway and the I-25 east Frontage Road. Please watch for vehicles entering and exiting the site throughout the duration of construction. Upon project completion, the area will be returned to its previous state; the asphalt will be removed and the area will be re-graded and seeded.


Safety for drivers and workers is our top priority during construction.
