TRAFFIC/TRANSIT TODAY: Tuesday updates and alerts, including Highway 99 lane closures

6 AM: Good morning! This is the first morning commute since the lane closures on Highway 99 began north of downtown, so we’ll see today how/whether they affect traffic. The basics:

*Median lanes close in both directions between the Aurora Bridge and just north of Mercer Street.

*An additional lane will close at night and during several weekends including Jan. 23-24.

*All traffic may use the southbound bus-only lane during the first phase of this work. Drivers should use caution since buses will travel – and stop – in the outside lane with other vehicle traffic.

We’ll be watching the traffic in and from West Seattle, of course, as always. If you see a problem we haven’t mentioned yet, and you are *not* driving, please text or call our hotline, 206-293-6302.

8:57 AM: So far this morning, regional traffic reports indicate that those north-of-downtown lane closures have backed up SB 99 more than NB 99. West Seattle and vicinity, meantime, has been incident-free this morning, at least according to everything we monitor.

I didn’t notice traffic slower this morning going into downtown at 7am on the bus. I’m worried about it. I wonder how far south the SB99 is impacted?

From the traffic-camera views, it appeared to be southbound, at the work zone and northward.

I am so confused about these lane closures. I thought both NB and SB 99 would be reduced to 99 at Mercer. I traveled NB this morning and the lanes were only reduced to 2 lanes and causes no issues. SB did look more backed up, but it usually looks backed up.
