Main Street Reconstruction

The city retained HDR Engineering to complete a technical analysis of future transportation enhancements on Main Street. The project seeks to improve pedestrian facilities and vehicular flow throughout the corridor.
Short-Term Enhancements
Goals:
- Improve vehicle progression along the corridor
- Reduce travel times
- Improve pedestrian space where possible
- Invest in a roadway configuration that will operate well in future years
Short-term improvements:
- Removed pedestrian scramble to improve traffic flow
- Adjusted pedestrian crossing times to better serve pedestrians
- Worked with ITD to improve signal technology
- Implemented coordinated signal timing
Long-Term Enhancements
#1 – Current conditions / no change

#2 – Add left turn lanes at Sun Valley Road

Currently, Main Street consists of 4 travel lanes with no designated turn lanes. This option would add a designated turn lane.
Benefits:
- Remove split phasing
- Reduces congestion
- Serves all traffic
- Design year traffic sees comparable travel times to today
Drawbacks:
- Increase in pedestrian crossing distance at Sun Valley Road Intersection
- Tight turning movements for trucks at Sun Valley Road
- Removes parking on two blocks

#3 – Lane Reconfiguration
Currently, Main Street consists of 4 travel lanes with no designated turn lanes. This option would have 2 travel lanes with 1 designated turn lane.
Benefits:
- Remove split phasing
- Shorter pedestrian crossings
- Much wider pedestrian and sidewalk areas could be built
Drawbacks:
- Congestion on Main Street would increase
- Cannot serve all traffic in the peak period
- Waiting vehicles could extend 3 blocks or more on Main Street and 2 blocks or more on cross streets
