IMPACTS TO TRAFFIC

Driving lanes will be open throughout the duration of the project, except for a period in spring/summer 2024 when a section of the roadway will be closed to thru traffic at the Union Pacific RR overpass for five to seven weeks. During this time, through traffic will be diverted to Route 100 as the designated detour.  Other short-term lane closures are anticipated at various locations and times.
