    Heads up the backup on 509 is already back to at least 112th.

    For the bus, looks like the detour added about 10-15 minutes to the #113.  The 113 leaving 26th/ 116th @6:00am arrived to 3rd and Marion at 6:48 (got downtown at the same time the RR H arrived: the RR H left Westwood Village at 6:23am)

    Does anyone know why the road is closed at Cloverdale and not a little further north so that the West Marginal exit could be used?  I drove south on 509 at 8am and the backup was past 128th.

Sorry, comment time is over.
