Went to the Open House for the Puget Sound Gateway Program in Fife last night. This one focused more on 167 (I missed last week's 509 open house in Seatac). The visualizations will be online within the next two weeks, but there are a few things that I saw that have changed from the previous phase one
- Ramps to and from the west at Meridian (where 167 currently ends) have been shelved. There's a $15mil budget gap
- The phase one interchange where the 5/167/509-Spur meet will be a partial diverging diamond instead of half diamond. It's hard to explain the design -- the visualizations make better sense.
- The entire route will be four lanes. WSDOT's Craig Stone said that "lanes are cheap, interchanges are not". I guess they found the money to have four lanes, but couldn't afford fancy interchanges.
- North Levee EB will turn into a on-ramp towards 167 NB (as it does now), but will instead utilise the old on-ramp that was never torn up.
- The oddly-shaped on-ramp from Meridian (the current one) was built in that manner due to a historic tree. One of the interns suggested that I cut it down for them.
I also learned that the stub-ramp at the end of the departures deck at Seatac was built for a south access road. According to Craig Stone, the 509's phase one design will include provisions for a future south access road. The South Access Road has been planned for some time, but always shelved due to funding and lack of a proper place to dump all the traffic. The southern extension of the 509 will finally provide a good place for the end of the access road.
This is the stub ramp in question:
