How will this project affect congestion in future years?
WSDOT, through computer modeling, estimates that if this project is not built, traffic congestion will average 3 hours a day by 2010 and 4 hours a day by 2020. By comparison, if the project were built, we would see about 0 hours a day of congestion in 2010 and 0 hours a day in 2020. Average afternoon travel speeds in 2010 and 2020 would be 44.5 and 39.5 mph, respectively, if the project is not built. But speeds would be 55 mph for each forecast year if the project is constructed.
