ROADS/BRIDGES: Flyover project to connect high-occupancy toll lanes in Seattle area

The new direct connector is expected to help drivers avoid weaving in traffic and to reduce congestion

September 30, 2016

Ground will be broken on a new flyover bridge Thursday at the I-405/SR 167 interchange in Renton, Wash., one of the most congested commuter routes in the Seattle area.

The Washington State Department of Transportation is building a new flyover ramp connecting traffic going north off the Valley freeway at about Southwest 23rd Street and getting on I-405 around Benson Road. 

The new direct connector will bridge the high-occupancy toll lanes on SR 167 to the carpool lanes on I-405.

The goal is to help drivers avoid weaving in multiple lanes of traffic several times and is expected to ease the congestion quite a bit.

The total price tag is about $116 million dollars and it's set to be completed in the summer of 2019.
