Highway Network Updates

Changes due to Amendment #3

Minor updates to the highway network were made to accommodate projects from WFRC’s adopted Amendment #3 2023-2050 RTP. Figure 1 shows the areas that were updated for Amendment #3, followed by a description of each project update.

Figure 1: Updated Lane and Operational Lane Fields (blue)

1200 West (Brigham City)

  • R-B-3 is a 1.6-mile widening project of 1200 West from Forest Street to Promontory Road / SR-13. This amendment will update the project from 2 to 5 lanes changing it from an operational project to a widening project and move the project from Phase 2 Need and Fiscal Constraint to Phase 1 Need and Fiscal Constraint.

Volume Comparison

The changes due to Amendment #3 resulted in slight changes to roadway volumes along corridors near the project areas. Figure 2 through Figure 4 show the impacted segments for the 2032, 2042, and 2050 fiscally constrained scenarios.
