Full Ramp Closures Set for I-25 Overlay Project from C-470 to Belleview Avenue

June 21, 2018 -


ARAPAHOE COUNTY — A series of temporary full-ramp closures on Interstate 25 are expected to take place on the I-25 Overlay: C-470 to Belleview Avenue project through October. Full ramp closures will be temporary and only last during work hours. Impacted ramps will include northbound and southbound on- and off- ramps at various intersections at I-25.

Ramps that will be impacted now through October are listed below:

  • Belleview northbound off-ramp and southbound on-ramp
  • All four Orchard Road on-ramps and off-ramps
  • All five Arapahoe Road on-ramps and off-ramps
  • All four Dry Creek Road on-ramps and off-ramps
  • All five County Line Road on-ramps and off-ramps
  • C-470 southbound off-ramp and northbound on-ramp

Crews will be milling and paving the roadway during these full-ramp closures. Detours for each closure will be displayed near the project zone. Motorists can visit the interactive road work map on COTrip.org to keep up-to-date on ramp closures each week.

Since April, crews have been conducting bridge deck work, median barrier repairs, and milling and paving on I-25 between C-470 and Belleview Avenue. Work is expected to last through winter 2018 on this project.


Motorists should expect various lane closures on northbound and southbound I-25 during work hours on this project. Typical hours will be between 8 p.m. and 5:30 a.m. Sunday through Thursday. Weekend work may occur as needed. There will be a speed reduction through the project zone to 55 m.p.h. during work hours.
