Spokane Valley Council Adds Second Lefthand Turn Lane At Theirman Road

Spokane Valley is adding a second lefthand turn lane at Thierman Road onto Sprague Avenue despite warnings from traffic engineers that it would increase the risk of sideswipe collisions. The City Council last week decided to proceed with the $14,000 plan to convert the inside northbound lane to a turn-only lane and give drivers in the outside lane the option of either making a left turn onto Sprague as well or continuing through the intersection.

It’s supposed to ease potential traffic buildup at the intersection but engineers say it could cause sudden lane changes as it forces drivers into a lane that quickly becomes part of an I90 onramp.
Here's more on this issue and why some councilmembers say they're not worried about added safety issues despite what staff recommends.
