From Peg Nielsen at SDOT:

No details except that there is a report of a water main break at 6th Ave S and S Spokane St. Seattle Police are on the scene directing traffic. Avoid the area to avoid delay.

Any later updates, we’ll add to this item.

3:20 PM UPDATE: Just in from SDOT and SPU:

A watermain break in the vicinity of Sixth Avenue South and South Spokane Street this morning prevented traffic that was exiting from I-5 from turning right at Sixth Avenue South. The emergency work will pause by 3 p.m. today and all traffic movements will be restored during the peak period. Crews from Seattle Public Utilities plan to resume work at 10 p.m. this evening and work through the night. They plan to keep all lanes open to traffic tonight, if possible.
