Interestingly, when WSDOT first started the project and solicited consulting parties, there were NO PHOTOS of the bridge made available by WSDOT. That's not good in itself, but worse there were no photos on BridgeHunter. Nobody even knew what the bridge looked like, so it was hard to decide whether it was worth becoming a consulting party or not.

Usually WSDOT waits until a bridge gets to deficient status before replacing so they can get more federal funds. I really do not know why they need to replace as their plans call for a 4 lane WA 9 in the future which could easily be put to the west. The road could just serve the few houses nearby and bridge remain in place. But this is WSDOT, an agency that has saved only one bridge in its entire history and seems content on resting on those laurels.

Interesting note, they took images in August a few days after I did, and they are not surprisingly worse. You cannot show the best in something when you want to get rid of it no?

And Bickford on the plans ... a big player in the county. Streets are named after him.

Section 106 is ongoing for this bridge. I added the photos WSDOT has provided to consulting parties, and am attaching a plan sheet showing the bridge with original railings which was also included among the materials.
