Remember that complicated web of wires above Broadway we wrote about earlier? SDOT will be adding to it this weekend as work again redirects traffic in all directions at the intersection of Madison and Broadway:

SEATTLE — The Seattle Department of Transportation (SDOT) will close the intersection of Broadway and Madison Street from 6 a.m. to 10 p.m. on both Saturday and Sunday, March 22 and 23.  This closure is for electrical installation work associated with the First Hill Streetcar Project. Police officers and traffic flaggers will be present to ensure access to businesses and residences in the area and the following detours will be provided:

When complete, the First Hill Streetcar Line will have ten stations along a two and one-half mile route from South Jackson Street and Occidental Avenue South to Broadway and Denny Way. The City of Seattle is developing the First Hill Streetcar in partnership with Sound Transit, with funding provided through the 2008 voter approved Sound Transit 2 (ST2) transit expansion plan.  Completion is planned for mid- 2014.

The new streetcar route is expected to be complete and ready to provide its first service later this year.
