Full Closure of Yosemite Street Expected End of April-Early May 

Please be aware that a full closure of Yosemite Street in both directions is expected to begin at the end of April between Xanthia Street and Arapahoe Road, for an estimated 10 days. Following that closure, crews will move to the north section of Yosemite Street and both directions of Yosemite Street between Arapahoe and Yosemite Circle will close. This closure is estimated to begin early- to mid-May.

Access to businesses may be temporarily altered, however one entrance will be maintained. This full closure enables work to be done in shorter time frame; and avoids the need for what would have been approximately eight weeks of rolling lane closures, which would continually shift traffic and change conditions for drivers.

All work is weather dependent, and due to possible snow coming in this week, the schedule may change. We will post exact closure dates when CDOT notifies the City of these specifics.

Project Background:

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 

2017 Street Rehabilitation Program

Street Rehabilitation 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.
