SR 171 - Moses Lake - Pedestrian Improvements - Complete June 2014


June 2014

  • Construction began April 21, 2014 and was complete on June 6.

This pedestrian safety project upgraded four existing pedestrian crossings and installed four new ones along a 3-mile section of Broadway Avenue in Moses Lake.

Why is WSDOT upgrade existing pedestrian crossings and provide new ones along SR 171?
This section of Broadway Avenue in Moses Lake has a history of pedestrian/vehicle collisions. 

In five years before construction, there had been seven vehicle-pedestrian collisions here. Three of them resulted in fatalities, two produced serious injuries and two more, lesser injuries. WSDOT partnered with the City of Moses Lake on this grant-funded project to increase safe crossing opportunities for pedestrians on SR 171.

The End Result
The pedestrian crossings at these four locations had the existing flashing beacons replaced with new rectangular rapid flashing beacons (RRFB). 

  • Driggs Drive at MP 0.35 
  • Burress Avenue at MP 0.82
  • S. Western Avenue at MP 1.65
  • Dogwood Street at MP 2.51

The new, rectangular RRFB lights have  produced 80% to 90% compliance in vehicles yielding to pedestrians at high risk crossings. The push buttons were replaced with audible push buttons to aid the visually impaired.

These four intersections had new crossings installed with RRFB's, audible push buttons and illumination.

  • Melva Lane at MP 0.20
  • Gibby Road at MP 1.46
  • Gumwood Street at MP 2.32 
  • Third Avenue at MP 3.46
