A letter outlining some lane closures on I-45 was sent to residents of Tiki Island. Roger Stone (all-around good guy and commuter guru) helped us track down updated details fom the project engineer at Traylor Bros., the people building the new causeway. The plan is to get all traffic on the new bridge to allow for the dismantling of the old spans. On May 30 (the Tuesday after Memorial Day) at around 9 a.m.–after the morning rush–the southbound lanes leading to the causeway will go down to two lanes so that traffic can be diverted to the new bridge. It’ll stay restricted to two lanes until June 2, while they rework the Tiki Island exit. Expect a morning rush hour back up at the bridge from 5-31 through 6-2. The good news, they’re three months ahead of schedule and should be done with both spans by Summer 2008.
