The Brooklyn Eagle reports that the Montague Street tunnel will reopen in October. The passage had closed for repairs last year to fix damage done during superstorm Sandy. Service changes were made for the duration on the R line. The MTA shared an update, the paper reports, at a meeting of CB10 recently.
Brooklyn Eagle: Workers are removing all of the wiring, lighting, signals, and concrete in the tunnel, MTA officials told the Traffic and Transportation Committee. The tunnel has been striped bare, right down to its cast iron ring, installed 100 years ago.
Workers are busy inspecting the tunnel for leaks and are stopping those leaks through a chemical grouting injection process, according to the MTA. During this process, over 2,000 of the original bolts holding together the 18 foot diameter cast iron tunnel rings and liner are being replaced with specially manufactured grout bolts. Before the project is complete, it is estimated that more than 6,000 high strength steel bolts will be replaced.
The repairs are, in reality, a complete rebuilding of the interior of the tunnel, according to Cruz, who called the work “an amazing feat of engineering and logistics.”
