    Project: E. 88th Avenue Widening

    The city is conducting an Environmental Assessment (EA) along this 1.6-mile stretch of E. 88th Avenue between Highway 2 and I-76 in order to determine the environmental impacts of a proposed project. This project includes improvements to the Rosemary intersection. The final EA will present the preliminary design, evaluate environmental impacts and identify next steps for project implementation.

    We received your feedback in 2019, and based on our findings from community and agency scoping, it is proposed that the project will include the following elements:

    Elimination of Bridge Over the Rail Road Crossing

    During the development of the EA, the proposed grade separation at the UPRR was examined. Based on feedback from the public, the high cost, and other higher priority grade separation needs within the city, this crossing will be improved as an at-grade crossing.
