Every Monday morning, I do a Dr. Gridlock blog posting called "The week ahead for traffic, transit." I try to include information about Ohio Drive, since so many of you are stuck in that traffic during the National Park Service reconstruction program.
Here's what I said this morning. Let me know if it's clear and if it addresses your questions:
The current phase of the project, Phase III, is scheduled to be done around the middle of the month. It includes replacement of all drainage, curbs and sidewalks. The sub-base of the roadway is under repair.
When Phase IV begins, it's scheduled to last about two weeks. To start, work will focus on the center of the roadway. Jersey barriers will create an island, where construction will take place. After that work in the middle, all surfaces will be repaved at night, during a complete closing of the roadway. If all that goes as scheduled, the project will be done around the end of October.
Meanwhile, morning rush hour traffic will remain inbound only. During the afternoon rush, Ohio Drive will be two lanes outbound only. There may be full closings of the roadway from 7 p.m. to 5:30 a.m. nightly.
