I-205 needs two more interchanges. One for NE 18 St, north of Mill Plain Blvd. And the other for NE 138 St in the Salmon Creek Area.
Also SR 14 needs a full third auxiliary lanes. From I-205 to SE 164 Ave. There is already full auxiliary lanes between SE 164 Ave and SE 192 Ave.
Good news from the future for SE 18th St., but they seem to be stalling on the project. I don't think there's enough ROW for an intersection for NE 50th Ave or NE 119th St. (The two overpasses between 136th Ave. and Padden Pkwy).
WA-14 does really need a third lane (I wouldn't mind an HOV or HOT lane), but traffic demand isn't too big on those highways yet. It only bunches up at the Interstate Bridge.
What I want to see is WA-500 extended all the way to NE 162nd Ave. Right now, the freeway portion turns up to Orchards and ends on 4th Plain. I find it odd that they rerouted WA-500 an extra 2 miles through Padden Pkwy.
