The spring and summer months are the busiest time for construction. Be sure to keep an eye out for major construction projects that may affect your travel routes. Below is an overview of current major construction projects in the City of Centennial.


Arapahoe Rd. / Waco to Himalaya Widening Project

Contact: Travis Greiman
Start Date: August 3, 2015
Estimated End Date: Mid 2016

The City of Centennial, along with project partners Arapahoe CountySoutheast Metro Storm Water Authority (SEMSWA), and the City of Aurora, have collaborated a plan to increase the capacity, improve safety and mobility through this specific segment of Arapahoe Rd.

Approximately 1.5 miles of Arapahoe Rd., between Waco St. and Himalaya Way, will be reconstructed and widened from the existing two-lane section to an interim four-lane section through the City, and a final six-lane section through unincorporated Arapahoe County. Three intersections with existing traffic signals will be redesigned. Several drainage outfalls exist along the project. Improved outfalls will be designed and constructed in coordination with SEMSWA. Existing overhead electric lines on both sides of Arapahoe Rd. will be undergrounded to accommodate the wider roadway section. The design of these facilities will be coordinated with Intermountain Rural Electric Association (IREA).

I-25/Arapahoe Road Interchange Reconstruction Project (CDOT)

Contact: Project Website |​ Email |​ Project Hotline: (720) 580-2525 
Start Date: May 9, 2016
Estimated End Date: Summer 2018

This project consists of replacing the I-25 bridge over Arapahoe Road and other interchange improvements designed to reduce congestion and improve traffic operations and safety. This is a CDOT project, in partnership with Arapahoe County, the Cities of Centennial and Greenwood Village, and the Southeast Public Improvement Metropolitan District. 

Commuters should expect nightly lane restrictions (8 p.m. to 5:30 a.m.) on north and southbound I-25 between Belleview Avenue and County Line Road including various northbound/southbound ramp closures. Lanes will be restricted east and westbound Arapahoe Road between Dayton Street and Syracuse Way/Spruce Street (7 p.m.to 5:30 a.m.) for median work, to set barrier and re-stripe. These overnight impacts will occur for the next several months. Ongoing sidewalk closures on the north and south side of Arapahoe Road will be necessary to accommodate lane realignments. One pedestrian access route will be open at all times. Work on re-routing the frontage road in the northeast quadrant of the interchange will begin in May, as well as a closure of Boston Street for a utility relocation (one direction will remain open). Business access may be temporarily altered at times but will be maintained.

Typical Daytime Lane Configuration During Construction:

Five through lanes on northbound and southbound I-25
Three through lanes on Arapahoe Road
Single left turn lanes on Arapahoe Road and Yosemite Street

Street Rehabilitation Map

Crack Seal Program Map

Mill and Overlay - Streets receiving a mill and overlay treatment will have the surface of the road milled for a portion or the entire width of the street and a new asphalt surface constructed.

Concrete Replacement - Streets receiving mill and overlay will also receive concrete rehabilitation before the pavement treatment. This effort repairs broken curbs, gutters, sidewalks and other concrete structures that if left unrepaired will shorten life of the major rehabilitation investment. As part of this work, curb ramps will be repaired and brought to current Americans with Disabilities Act (ADA) standards and the removal of concrete bus pads on E. Dry Creek Road.

List of streets scheduled for Mill and Overlay 

Hot In-Place Recycling (Heater/Repave) - Street segments receiving this treatment will have the existing pavement heated, re-mixed and placed, and finally topped with new asphalt in one continuous process. This treatment is environmentally friendly because it reused existing materials and significantly less natural resources. S. Buckley Rd from Smoky Hill Rd. to E. Orchard Rd.​ 

Surface Treatment (Slurry Seal) - Streets that have less severe cracking and display less distress can be preserved with a slurry seal. When used properly, this treatment will extend a street's pavement life five to seven years.
