Broadway is now due to reopen in November, after contractor Auldyn was granted an extension.

Originally due to reopen on September 8, the major junction’s opening has been pushed back to the end of November.

Broadway closed on May 25 to allow for work on the new roundabout, complete service connections and crossing points.

The Department of Infrastructure has since updated the plans, with the delay being put down to the complexity of replacing the gas main.

Due to its age and condition, the historic gas main had to be kept live to ensure an uninterrupted service to customers but this proved extremely problematic at times.

A DoI spokesman said: ’As a precautionary measure the contractor, Auldyn Construction has applied to extend the closure on Broadway until the beginning of December. Early investigations have shown how fragile the pipe work is.’

The government’s road closure notification website says the extension has been granted until November 26.
