Many said it couldn't be done in the timescale - but Highways England have proved the doubters wrong- by some margin.
The M27 between junctions 3 and 4 at Romsey has now fully reopened in both directions.
The motorway was scheduled to reopen at 5am on Monday morning but has reopened 16 hours early.
It follows a weekend closure of the M27 to demolish the western half of the Romsey Road Bridge
“We are pleased to say that the demolition of the western part of the Romsey Road bridge was completed ahead of schedule, so the M27 has opened earlier than expected. I would like to thank road users, residents and businesses in the area and along the diversion route for their patience while we carried out this important work.”
The project team will now begin building the new bridge deck at the site compound near the M27. The next weekend closure, to install the new bridge deck, will be between 26 – 29 April 2019.
