I-84 / US-89 Interchange | Weber County | Environmental Study

Study Complete

We have conducted an Environmental Assessment (EA) consistent with the National Environmental Policy Act (NEPA). The EA, as amended, and the Finding of No Significant Impact (FONSI) have been approved and the project can proceed toward final design and construction of the Selected Alternative.

Where do we go from here?

To move from a study to a construction project, the following steps must occur. (Timelines vary for every project):

Planning: The project is added to the Statewide Transportation Improvement Program (STIP).
Funding: The project is prioritized and receives funding.
Design & Construction: The project enters final design, followed by construction.

Phasing

UDOT may construct the Selected Alternative in multiple phases as funding becomes available. Potential phases could include:

Phase One

Implement a new single-point urban interchange (SPUI) at I-84 and US-89
Relocate and realign the UPRR railroad bridges

Phase Two

Build the new commuter bypass lanes from South Weber to South Ogden with a southbound flyover ramp at Harrison Boulevard
Construct shared-use paths with a Weber River crossing
Improve the Skyline Drive intersection

Potential phases could be combined or modified to accommodate available funding.
