Getting to West Seattle and Sodo from Beacon Hill is going to get more complicated, starting tonight. As we’ve reported previously, the Fourth Avenue South off-ramp from the West Seattle viaduct will be closing permanently starting at 10:00 pm tonight, eventually to be replaced by a new off-ramp at First Avenue South.
Spokane Street (at surface level) will be closed from First to Sixth avenues, though business access will be preserved. The eastbound lanes will reopen sometime in 2010, and the westbound lanes will be closed for the duration of the project.
In more short-term closures, the northbound I-5 ramp to the West Seattle Bridge will close at 10:00 pm tonight and reopen at 5:00 am on Monday. The ramp from westbound Columbian Way to the West Seattle Bridge will also be closed for the entire weekend.
Fourth Avenue South will be closed entirely between South Horton Street and Industrial Way South from 10:00 tonight until 5:00 am tomorrow morning, with possible further restrictions as needed, and the same stretch of road will be reduced to one lane in each direction for at least a month after that. This may include full closure of northbound lanes at night.
