The Dept. of Transportation issued a bid solicitation last month for additional repair work on the Brooklyn Bridge with no connection to the current major rehabilitation project.

The $600 million dollar construction project currently underway is the first major repair to the bridge since 1958. After being delayed for decades due to the high cost, the bridge earned a “poor” condition rating by the state in 2007, and renovations began in 2010.

The project has faced several obstacles since breaking ground. Earlier this year, completion was pushed back once again following the discovery of 3,000 structural “flags” on the 1,595-foot bridge, causing the budget for the project to increase nearly $100 million from the original $508 million. Completion had previously been set for April of the year, but is now expected some time in 2016.

The new construction will not be part of the larger project, and will not commence until the initial rehab has been completed.它将包括工作涉及”方法拱门,towers, ramp substructures and miscellaneous repairs” on both the Brooklyn and Manhattan sides of the bridge, per the bid solicitation. The repairs are scheduled to begin in fiscal year 2019 and will continue for roughly three years.

“Its beauty and iconic status alone can’t keep the 132-year-old Brooklyn Bridge in a state of good repair, said NYC Transportation Commissioner Polly Trottenberg in a prepared statement to Capital New York. “That’s why DOT’s work is never complete when it comes to providing TLC to this great structure and the nearly 800 other bridges we own and operate.”

Bids for the new project are due Sept. 21.
