City transportation staff presented a concept for rerouting a roadway near South Bonnie Brae at Brush Creek and explained how the plan ties into a proposed at‑grade UPRR crossing.
Chandra, Transportation Services, said the exhibit presented is a concept the city will submit to Union Pacific for a crossing near SH‑377 and that the land for the alignment was dedicated by the Sagebrush development in 2020–21. She told the committee the plan is not a final design and that it is confined to the dedicated right‑of‑way.
When asked why the city proposes to close two crossings, Chandra explained that UPRR requires closure of two crossings to add a new crossing: “UPRR has a rule of you have to close 2 crossings to get a new crossing,” she said, and added that the existing crossings are skewed, low‑volume and “already unsafe.” Staff said the new crossing would be an at‑grade crossing with quad gates, traffic signal preemption and quiet‑zone treatments similar to other city crossings.
Committee members asked whether the alignment would sacrifice green space; staff said it would not. Staff also noted that the planned crossing and intersection will include signalization and railroad preemption and that future traffic analyses (TIAs) would model expected traffic flows as projects progress.
Why it matters: the crossing and associated road realignment affect future connectivity in the area and are subject to railroad approval and safety requirements; the UPRR requirement to close crossings to permit a new crossing is a determinative constraint on alignment choices.
