Reed's Island bridge


Data I can find says this bridge was built in 1899 opening Reed's Island for development. NBI lists it as 1940. Technically, Reed's Island is no longer an island, with a land bridge at the south western end. The current Wailuku channel flows on the north side and Waikapu stream flows along the south side in an old Wailuku channel. Waikapu stream flows under the bridge just before joining Wailuku river at the north east end of the "island".

Reed Island bridge

Looks like seismic upgrades are the excuse for modernizing this old span.

"The wooden deck will be replaced with steel beams and a steel grating deck. Concrete rock anchors and micro-pilings, as well as lateral structural steel bracing members, will be installed to strengthen the deck and bring it up to speed with earthquake code requirements."
