Elm Street bridge plan

Why The east span has been down to one lane since the spring inspection. The expansion joints are letting water through to the bearings, and the deck lighting on the walkway side is mostly dark. The school buses use this bridge, so both lanes have to be open again before next fall. What it needs New expansion joints on both lanes. See Site notes . A patch or a wrap on pier 2, decided after the diver's inspection. New deck lighting, done by a contractor. Fresh paint on the railings once the heavy work is finished. Budget The city set aside 1.2 million for the whole job. The joints are about 640,000, the lighting quote should come in near 90,000, and the rest is the pier, the paint and the traffic control. Order of work Finish the report and get it signed off. Close the north lane, keep the walkway open. Joints on the north lane, then switch traffic and do the south lane. Lighting and railings. Reopen both lanes and watch the joints through one winter before calling it done. The closure sketch is on the whiteboard. The board has the jobs.

Site notes

From Tuesday's walk of the east span with the contractor and one very patient inspector. The joints Both joints on the north lane are cracked through the seal. Water runs straight onto the bearings below, which is where the rust started. Pier 2 Spalling on the upstream face, about two feet across. Nothing structural yet, but the diver needs to look below the waterline before we pick a patch or a wrap. Drainage Three of the deck drains are blocked with leaves. Clearing them is a morning's work and buys the joints some time. Lighting Seven of the twelve walkway lights are out. The wiring is original, so a new run is cheaper than chasing faults. Still need the quote.

Why

The east span has been down to one lane since the spring inspection. The expansion joints are letting water through to the bearings, and the deck lighting on the walkway side is mostly dark. The school buses use this bridge, so both lanes have to be open again before next fall.

What it needs

New expansion joints on both lanes. See Site notes.
A patch or a wrap on pier 2, decided after the diver's inspection.
New deck lighting, done by a contractor.
Fresh paint on the railings once the heavy work is finished.

Budget

The city set aside 1.2 million for the whole job. The joints are about 640,000, the lighting quote should come in near 90,000, and the rest is the pier, the paint and the traffic control.
