Design concept recommended for S-Curve, West Main, 3rd and 4th streets in downtown Sterling

March 17, 2016 - Northeastern Colorado/CDOT Region 4 - Additional public outreach planned in coming months

LOGAN COUNTY – A preferred design configuration is now recommended for a new S-Curve along vacated railroad tracks connecting the intersection of W. Main/Division/N. 5th Street with Chestnut/4th Street. The project also recommends conversion of 3rd and 4th streets from one-way to two-way between Chestnut and Broadway, with 3rd Street becoming Highway 6/138.

CDOT, with input from the Town of Sterling, local stakeholders and the broader public, led an alternatives screening process to determine roadway alignment and intersection reconfiguration. The screening process was organized into a set of options for each improvement area (the intersections at W. Main/Division/N. 5th Street, Chestnut and 4th Streets, Chestnut and 3rd Streets, the S-Curve alignment and conversion of 3rd and 4th to two-way). The following describes the design:

  • W. Main/Division Street/N. 5th Street: Signalized T-Intersection of the S-Curve into Main Street with a closure of North Division.

  • Chestnut/4th Street: Right Turn only from existing northbound 4th onto Chestnut, and Right Turn only from westbound Chestnut/S-Curve to 4th and Chestnut; stop signs and left through movement at Poplar Street.

  • 3rd/4th Streets: Conversion from one-way to two-way from Chestnut to Broadway, with 3rd Street becoming Highway 6/138.

  • W. Main West: Reconstructed from approximately 8th Avenue (tying into the recently completed reconstruction project) east to Division Street. Installation of raised medians and utility improvements are planned; no modifications to lane width or sidewalks are anticipated.  

As part of the next phase and in compliance with the National Environmental Policy Act (NEPA), CDOT will initiate a Categorical Exclusion to evaluate these and other resources in greater detail. Final design and right of way acquisition will proceed through 2016 and construction is anticipated to begin in early 2017. Public outreach will continue throughout the project.
