Hwy 144 North and South of Willis is currently a 4-lane undivided roadway
Proposed to be changed to a 3-lane section to match section around Willis
One lane in each direction with a center turn lane
2016 Volumes Range from 5,000-9,000 Vehicles per Day
Iowa DOT completed “Statewide Screening for Potential Lane Reconfiguration” report in 2017
Several roads throughout the state identified as potential for 3-Lane
Highway 144 recommended for lane conversion based on vehicle volume and crash history
3-lanes recommended for consideration by IDOT when volumes are less than 16,000 vehicles/day and crash rate greater than state avg.
Perry's crash rate is 3 times the state average.
Grant Funding secured to repave & restripe Hwy 144
Council voted in 2018 to support the grant application
Success in Perry
Success with other 3-lane restriping projects in Perry
Hwy 144 from Willis to Bateman Restriped in 2016
Before project this section had 20 crashes in 3-years
With 7 injury crashes, including one fatal
After project this section had 6 crashes in 3-years
With no injury crashes
Perry has seen a 70% reduction in accidents
Why This Project?
Concerns from Residents
N. of Rawson St
23 crashes in since 2012
98% of crashes: rear-end, broadside, angle
20% are injury related
Limited Sight Distance when pulling out from side streets
From 2013-2017 the First Street Corridor had 71 Crashes totaling $332,060 in Personal Property Damage.
Improved Vehicle Safety
Improved Pedestrian Safety
Reasonable driver sets the speed instead of the unreasonable driver
Improved Emergency Response Time
Reduced Number of Conflict Points
The main issue is that the left (inside) lane is shared by higher–speed through traffic and left–turning vehicles. Road Diets reduce the number of vehicle–to–vehicle conflict points that contribute to rear–end, left–turn, and sideswipe crashes.
Improved Sight Distance
Safer Street Crossings
Safer Pedestrian Crossings
After: "Crossing only one lane of traffic at a time reduces the risk of crashes and serious injuries"
Potential increased delay at unsignalized access points
Reduced passing opportunities
Slow Moving Vehicles
Possible Increased Travel time
Learning curve of new layout and initial confusion with change.
A public meeting was planned to present the concept plan and gather feedback
May 23rd from 5-7 at La Poste (1219 Warfors St.)
Modifications to the plan will be made in Summer/Fall 2019
Repaving/Restriping work is planned for Spring/Summer 2020
