SODO traffic alert this morning – 1st Avenue South is down to one northbound lane between Holgate and Edgar Martinez Way, according to KING 5, because of a big overnight water-main break. There may be fewer West Seattle drivers using 1st Avenue South right now anyway because of the ongoing Spokane Street Viaduct offramp closure, but if you’ve been getting off at 4th and cutting back over to 1st – you’re hereby forewarned.
