The City of Grand Junction will start construction on the Horizon Drive and G Road Roundabout Project on April 7, 2025. This project is part of the City’s continued investment in transportation improvements. Sunroc Corporation was awarded the contract that is scheduled for completion in October 2025.
Starting in April, Sunroc Corporation will begin staging route information and signage near the intersection of Horizon Drive and G Road / 27 ½ Rd. A temporary roundabout will be installed as a detour to safely convey traffic. Users can expect a delay in traffic as lanes will be reduced to a single lane and intermittent road closures implemented as necessary. All business access will be maintained.
The City of Grand Junction worked with the Horizon Drive Business Improvement District in 2012-2013 to complete a public engagement process focused on developing a vision for the Horizon Drive corridor that would improve traffic flow, increase safety, improve aesthetics with a One Percent for The Arts Program, and support economic development. The results of these planning efforts led to the construction of interchange improvements at I-70 in 2015 and 2016 by the Colorado Department of Transportation (CDOT). Subsequent corridor improvements included crosswalks (completed in 2019), pedestrian improvements, access control, and intersection improvements at G Road / 27 ½ Road.
In 2020, the City of Grand Junction worked with consultants to further develop the conceptual design for the Horizon Drive & G Road / 27 ½ Road Intersection. This included completing an operational analysis for the intersection and developing the horizontal geometry for a roundabout configuration that would address the capacity and safety needs of the corridor. The City of Grand Junction has
secured grant assistance from the Highway Safety Improvement Program administered through CDOT for the construction of the roundabout project.
