This is nothing short of amazing. Crews built a new Interstate 84 bridge in New York right next to the old one, then demolished the old bridge and slid the new one into place on a Teflon-coated track. Faster, cheaper, less disruptive to traffic. Read the Wired report here. Thanks to Jeff Leber for the heads-up on this.

The Port Authority is still waiting to hear from the Federal Transit Administration about whether it can waive the HOV requirements at the Wabash Tunnel for the duration of the West Carson Street construction project. This should be fairly easy, but recent history shows us that nothing in Washington, D.C., seems to come easy. (Cartoon: Jacob Shriftman)

The Pennsylvania Department of Transportation will hold a public meeting to unveil an intersection improvement project at Route 58 (East Main Street) and Route 173 (Liberty Street) in Grove City from 6 to 8 p.m. Oct. 30 in the council chambers of the Grove City Borough Building, 123 Main St. The meeting will include a brief presentation and display area, with citizens able to discuss the details with the project team. The project is tentatively scheduled to be constructed in late 2014 or early 2015.
