Project Goals
Improve Safety of Traffic flow (Vehicular and Pedestrian)
Control Excessive Traffic Speeding
Address Traffic Congestion and Queuing problems during School peak hours
Improve Drainage and inadequate Storm Sewer system
Project Needs
Excessive Speeding along 156th Street
171 traffic citations (2006); 199 citations (2007); 150 citations (2008); 135 citations (Jan-June 2009) Speed Records along 156th Street
for 2008 - 81 mph for 2009 - 59 mph
Speed – Drivers Cone of Vision
40 mph 40 mph 30 mph 30 mph 20 mph 20 mph
Project Needs
Poor Traffic Operations and Queuing during school peak hours.
Project Needs
Drainage – Open Ditches and existing storm sewer inadequate causing runoff and flooding.
Project Needs
Roadway – 156th Street Pavement rapidly degrading. No resurfacing or rehab done in the last 15-20 years.
Project Alternatives
No-Build AlternativeNo-Build Alternative
Current 2-lane section along 156th St 4-way stop at 156th St & Bennington
Rd Does not improve traffic operations,
excessive speeding and queuing issues
Does not improve safety of Pedestrian/ Bicycles
Drainage problems will continue to exist
Project Alternatives
Build AlternativesBuild Alternatives Widen 156th Street to a 3-lane roadway
with a center left-turn lane Provides additional capacity to handle future
volumes and queuing at School Provides a refuge lane for left-turning
vehicles Provides a transition area for medians and
landscaping – shorter pedestrian crossings Traffic Calming like Chicanes (curved
roadway) can be effectively incorporated to slow traffic
Project Alternatives
Incorporate ‘Traffic Calming’ elements to control excessive speeding Chicanes (Curved Roadway) Medians Landscaping, Trees Roundabouts etc.
Project Alternatives
Build AlternativesBuild Alternatives Install a Traffic Signal at 156th St & Bennington Rd
More Right-of-way needed to install exclusive left-turn lanes Volumes do not meet ‘Federal Traffic Signal Warrants’ till
2030 – No federal money can be used
Project Alternatives
Build AlternativesBuild Alternatives Install a Roundabout at 156th St & Bennington Rd
Excellent traffic control to reduce speeds (15-20 mph) Good pedestrian crossings – Shorter crossing distance with
refuge medians (one lane at a time) ADA compliant design Eligible for federal funding Functions as a ‘Gateway’ from South
North Segment
Chicanes
Curved Roadways to break drivers

Slow drivers
