Two of these lanes on Oak—and Granville St, since the 99 route follows it on the map—are used as parking spaces. That bridge is where the bottlenecks occur.

Oak Street Bridge is 4 lanes.
Look back in the thread for lane design for the bridge and Hwy 99.
In a nutshell, the Massey bridge has:
- 2 "climbing lanes" for trucks - bridge only
- 2 HOV transit lanes - veer off via ramp to Bridgeport Station before Oak St. Bridge
- 6 general purpose lanes that merge to 4 for Oak St. Bridge.
Here's the diagrams for the Oak St Bridge area from 2016.

I'm wondering if this is because the ramp is only one lane wide, so the buses need to stop to make sure no one else is on the ramp before proceeding? Probably a budgetary measure, but I don't have a problem with it. When the Oak Street Bridge is eventually rebuilt, I imagine the ramps will be rebuilt so that they slope downward as the bridge rises, to connect directly with Van Horne Way.
Second (in red), at the same location, I don't like how Bridgeport Road merges onto the highway at the same point that the HOV lane ends. Seems like that will cause traffic to slow a lot.
