KENNEWICK, Wash.- For more than a year driving has been clogged off and on along State Route 240 between Richland and Kennewick.
In June the traffic lifeline will move from four tightly packed lanes, to a separated eight lane highway.
The signs say it all: "Slow down. Work zone. Lane changing."
The 240 expansion project is almost two years old, but now, there's only a few more steps before completion.
The eastbound lanes still need to be paved and a roundabout is being installed on Columbia Park Trail.
Constant changes have caused problems, especially at night when drivers have struggled to notice differences.
In one instance an elderly man didn't notice he was going the wrong way until he was staring at the headlights of Kathy Elmgren.
"I was just lucky to not get in a head-on collision," Elmgren said.
The project will finish under budget and early, much to the help of drivers.
Nearly 60,000 drivers pass through that area each day, but during construction, people detouring the area have sped up work, and in a few months, two years of work will pay off with eight new lanes.
