Several traffic notes this afternoon: First, SDOT is sounding the alarm about Saturday’s Seahawks playoff game, since construction on the Spokane Street Viaduct and the south end of the Alaskan Way Viaduct are already causing some challenges in the area. Here’s some of what’s planned for that day:

To keep traffic moving, SDOT will re-open all lanes on Sixth Avenue S at S Spokane Street and also provide traffic control at the intersection of Fourth Avenue S and S Spokane Street. WSDOT is opening up a temporary crosswalk at First Avenue S and Railroad Way S and adding police officers to assist pedestrians. Motorists should, however, anticipate delays on First Avenue S between S King Street (on the north side of Qwest) and Royal Brougham Way (on the south side of Qwest) where the street is reduced to one lane of traffic in each direction to accommodate pile driving in the SR 99 construction zone.

For those who have asked – no, there will NOT be special Water Taxi service that day; it remains on a Monday-Friday schedule.

Second alert: The weekly regional construction update is out – and it just keeps getting longer. One item of note, heads-up for later this month – six more nighttime closures of the westbound Spokane Street Viaduct (meaning you won’t be able to get to the West Seattle Bridge from I-5 or Columbian Way on those nights) are ahead: Jan 19-21 and 24-26, all scheduled for 10 pm-5 am. (P.S. We had checked earlier today about a sign seen yesterday on the eastbound bridge exit to 99, about overnight ramp closures next week; SDOT tells us those have been postponed, so never mind for now.)
