CO 7 Cherryvale to 75th Street EA & FONSI

Environmental Assessment (EA) May 2008 - This Environmental Assessment (EA) evaluates the environmental, social, and economic impact of the proposed action for State Highway (SH) 7 between Cherryvale Road and 75th Street (approximately 2.2 miles). For this study, the lead federal agency is the Federal Highway Administration (FHWA) and the Colorado Department of Transportation (CDOT) is the applicant. This EA evaluates the impacts of the Preferred Alternative. This is compared against the No-Action Alternative. Finding of No Significant Impact (FONSI) October 2008 - SH 7 is a principal east-west arterial roadway serving as a commuter and intra-regional facility (see Figure 1-1 and Figure 1-2). To comply with the National Environmental Policy Act (NEPA), an Environmental Assessment (EA) was conducted to evaluate the reasonable alternatives that address the purpose and need for the project and assesses the impacts of implementing the proposed improvements. Two alternatives, the No-Action Alternative and the Preferred Alternative (build alternative) were evaluated in the EA. The build alternative was identified as the Preferred Alternative.

CO 59 Resurfacing from Seibert to Cope

CO 59 from Seibert to Cope - The project consists of overlaying the existing roadway with 2.5 inches of hot mix asphalt and in places patching degraded areas. In addition, various structures will receive rehabilitation work. This will include bridge railing, guardrail, signing, delineators, and striping. This will improve the roadway function and make it safer for traffic. Kit Carson, Washington Counties, Colorado Highway

CO 66 to CO 56

The design for North I-25 from Colorado Highway (CO) 56 to CO 66 will be prepared by Muller Engineering to implement phase 1 of the North I-25 Environmental Impact Statement (EIS) Record of Decision (ROD). This phase includes adding an additional Tolled Express Lane (TEL) in each direction of I-25 and reconstruction of two substandard interchanges: I-25/CO 56 and I-25/Weld County Road 34. Other design components include initial I-25 express bus and stations, intelligent transportation system (ITS) elements, numerous retaining walls and bridge reconstruction, and frontage road reconstruction. Improvements will be designed with the ultimate preferred alternative and other elements in mind, accommodating future widening but not necessarily providing all future lanes at this time.

CO 71 Resurfacing south of Limon

Colorado Highways, CDOT will begin a resurfacing project on a 37-mile stretch of CO 71, south of Limon, between mile points (MP) 63.8 to 100.83.

CO 392 Environmental Overview Study (EOS)

The CO 392 Environmental Overview Study identified a transportation solution supported by local and regional planning partners that identifies right of way, which must be preserved for improvements. This plan will be used by planners to set aside right of way as development occurs along the corridor. The CO 392 EOS study limits are from CO 287 to the west to Weld County Road (WCR) 23 to the east. Keywords: Studies, State Highways, Construction Complete
