Public Engagement

Theme #1Speed

16

•“Would recommend speed reduction at Ridgeway and Old Wildwood Rd. highway section. Better maintenance of brush control for visiability (sic) purposed off of Ridgeway and Old Wildwood Rd.”

•“I never understood why the speed limit changes from 30 to 45 as one approaches Stillwater Road from the east. Drives hit the gas and go high speed up the hill to Wedgewood Road where it changes to 40. Maintain 40 from Century Avenue to Stillwater Rd.”

Theme #2Wedgewood Drive Intersection

17

•“Wedgewood Drive - Traffic Light and Improved Crosswalk”

•“Great opportunity for great improvements! No stoplight. Reduce speeds. Traffic calming efforts: bump outs, warning lights, landscaping, narrow lanes. Roundabouts where allowed. Greening/beautification. Business development friendly designs.”

Theme #3Left Turn Lanes

18

•“I am in support of a left hand turn lane on to Old Wildwood Road from 244 west. I have been almost rear-ended too many times to count. Vehicles often travel on the shoulder in order to pass a car that is trying to turn left on to Old Wildwood Road.”

•“The Left Hand Lane on Birchwood Rd is much needed. I was rear-ended turning left back in 2004.”

Theme #4Pedestrian Crossings

19

•“There needs to be a pedestrian crossing here with center refuge and flashing lights (as per Mahtomedi Ave crossing 400 yards to the East and Neptune crossing) . There are a lot of pedestrians who use the lincolntown streetcar trl to get to Lake Links”

•“Prefer to have pedestrian crossing here (ridge way), don't need another one at view rd. When driving north on Wildwood and wanting to take a right on Old Wildwood, it wouldn't make sense to have to stop for pedestrians in that exact spot.”

Theme #5Causeway

20

•“Please provide design options and costs for current and future investment in the corridor for bike, runners, commuters and micro-mobility, for the city council and advocates to include: … Moving Guard Rails, narrowing car lanes and placing bike paths to north and south, outside of guard rails.”
