Langdon Street Bridge to Re Open 10-15-06

Langdon Street Bridge to Re Open 10-15-06 Montpelier Vermont


posted at 8:53 am Fri Oct 13th, 2006 by (Jen)

The project, as currently designed, consists of replacing the bridge deck with a pre-cast structure known as an Inverset bridge which is constructed of steel beam and concrete decking, tied together with steel diaphragms. The new concrete deck surface will be surfaced with a sheet membrane for protection and covered with asphalt pavement. The existing pony trusses will be completely rehabilitated off site, including the attached sidewalks super structure, and then reinstalled in their former position. The existing granite block abutment walls and bridge seat will be rehabilitated and prepared to support the new Inverset structure. To all appearances, the new bridge will be indistinguishable from the existing structure to most people, but the trusses will bear only the weight of the sidewalks, railings and pedestrians, not the entire bridge deck. Mr. Kitzmiller explained that this option was “selected because it maintains the character and look of the existing bridge”. It was also explained that construction impacts, and particularly project duration, were also thoroughly considered. Essentially, the project is similar to the rehabilitation approach used for the School Street bridge, except the School Street bridge trusses no longer support either the deck or the sidewalks
