The $1 billion Pulaski Skyway rehabilitation project that's left detoured drivers grinding their teeth for the last four years will be reopened in the next few weeks, state DOT officials said.

Motorists will get their first chance to drive on the new southbound lanes Monday after a weekend shut down of the Skyway. Southbound traffic will be shifted from the new northbound lanes so crews can remove temporary guardrails, do minor paving, and other work, said Stephen Schapiro, a DOT spokesman. The Skyway has been closed to northbound traffic since April 2014.

Once that work is done, northbound traffic can return to the Skyway, but DOT officials didn't give an exact date when that will happen. In March, officials gave a late Spring date after the reopening was pushed back three times.

"Once this work is completed over the next several weeks, the northbound lanes will be reopened," Schapiro said. "Once we have a better idea on timing, we will inform the public."
