The US-89; Antelope Drive Intersection Improvement Project will connect Antelope Drive from its current ending point in east Layton to U.S. Highway 89. The project is designed to improve greater east/west connectivity in Layton City. This project also adds a new frontage road that will serve as a collector for seven current access points on Highway 89. Construction includes the removal of the old roadway as well as the base materials it was built on. Crews will then build a completely new roadway integrating updated design and safety features, including frontage road, new intersection at Highway 89 and Antelope Drive. The project increases safety by closing 7 access points that will now be served by the new frontage road and the new signal-controlled intersection at Highway 89. By completing this project UDOT is able to optimize mobility in Utah's transportation system.
A companion project located immediately north of the Antelope Drive project will take place this summer at SR-193 and continue to South Weber Drive. This project involves creating a double left turn from SR-193 onto the northbound on-ramp. The on-ramp will be widened to two lanes and will merge into a new auxiliary lane when it joins US-89. The auxiliary lane will run the complete length of the project to South Weber Drive. Added safety features will also be added including median barriers located in the center of US-89 from SR-193 all the way to South Weber Drive.
The bid to construct the Antelope Drive Improvements was awarded to Staker & Parson Construction and preliminary construction activities are underway. The SR-193 to South Weber Drive project is being constructed by Granite Construction and work on installation of the new drainage system has started.
Construction Underway - Intersection and Drainage
The first phase of the Antelope Drive project has been identified by the contractor as the new intersection at US-89 where Antelope Drive will eventually join. The purpose behind starting at the intersection is to provide an access for construction vehicles to haul the fill for the Antelope Drive extension while avoiding the use of neighborhood streets. This will eliminate noise, dust, and heavy construction traffic on city streets.
The contractor built their project office just west of US-89 and north of 2100 N.
Drainage work continues from approximately SR-193 to near South Weber Drive of the east side of US-89. Note that particular attention is being paid to dust control. Concrete pipes have been put into place. Installation will begin occurring later in the week.
Roadway Design Illustrations
The accompanying illustrations will help you better understand the nature of the two projects located on US-89 in Layton and South Weber. While these are representative illustrations and do not reflect every detail of the project in its entirety, the overall approach to the project is accurate.
