Is new Manette Bridge roundabout too small for big trucks?

The in basket: I heard second hand at the dentist’s office Thursday that one of Kitsap Transit’s worker/driver buses had had a hard time getting around the new roundabout being opened at the end of the Manette Bridge in Bremerton. The driver had to back up to maneuver his way around it, the report said.

It might have resulted from the driver’s unfamiliarity with the just-opened roundabout, I remarked.

It reminded me that Gary Reed had e-mailed on Oct. 6 to ask, “Is the roundabout on the Manette-side sized to allow buses, semi trucks, and fire trucks to safely negotiate it, or will there be a vehicle length restriction?

“It looks pretty small,” he said.

The out basket: Jeff Cook, project engineer for the bridge project said at the time, “There are no length restrictions being imposed on the bridge.  The design vehicle for this particular roundabout was the longest bus in the Kitsap Transit fleet.

“Keep in mind there are two components of a roundabout when it comes to traversable areas.  The first is the asphalt itself.  The second is the truck apron.  The truck apron is the concrete circle between the asphalt and the roundabout stubwall.  By definition it is “a raised section…around the central island that acts as an extra lane for large vehicles.

“The back wheels of the oversize vehicle can ride up on the truck apron so the truck can easily complete the turn, while the raised portion of concrete discourages use by smaller vehicles.”

John Clauson of Kitsap Transit confirmed that a worker-driver bus had run into trouble getting around the circle. State officials called them Thursday,” John said,  “asking us to bring out a bus so they could see just where the problem was. Our experience during that exercise was the same as the Worker/Driver.” I’m not sure where this will lead.
