The police scanner is reporting a head-on collision between a semi and a wrong-way driver on I90 at the Sherman Avenue exit that has closed a stretch of the freeway and the 15th Street ramp. Apparently, a driver drove the wrong way on the Sherman Avenue ramp and struck the semi head-on. At least 100 gallons of fuel have spilled. The coroner and funeral director have been called. Sounds as though the semi driver survived. I caught the last of the scanner traffic. So I don't know more details. The ISP will have full details in the morning.
