At 8 a.m. this morning the Seattle Department of Transportation began repairing a severely damaged portion of Elliot Ave W, between W Mercer Place St. and W Prospect St., blocking off the two right northbound lanes. Because the work will involve replacing 18 inches of concrete and asphalt, which will need time to cure, the right curb lane will remain closed overnight and will reoppen for traffic by midday tomorrow, Thursday, October 5.
