Dynamic signs coming to Columbian Way next week

Expect construction delays at this location next week as new dynamic signs are installed.

The Seattle Department of Transportation will be installing new dynamic (electronic) messaging signs at several locations in the city next week, including South Columbian Way/14th Avenue South near the freeway ramps. The new electronic signs will provide improved traffic information to travelers.

The signs will be installed during the daytime next week, March 8 to 12. The work will start in Crown Hill and progress down the list to Columbian Way, which is last, so we can probably expect lane closures and construction slowdowns at Columbian and 14th from the middle to end of next week. Expect some delay and congestion during this time.

The other locations that will receive the new signs are in Crown Hill at 14th Avenue NW and Holman Road NW, 15th Avenue NW just south of Ballard High School, and on 15th Avenue West near the Magnolia Bridge.

We are not sure exactly what the signs will look like, but they may be similar to other dynamic messaging signs SDOT has previously installed in SODO. Here’s an interesting PDF from 2005 about the use of dynamic messaging signs by WSDOT on Washington highways.
