Osborne undertakes deck pour at M27 Romsey Road Bridge

With the first of the two original bridges successfully demolished, Osborne have started building the new structures which will support the new M27 Romsey road bridge.

The new abutments are being built close to where the old ones were, the piles required for the abutments are being installed by means of Bored cast-in-place piles, this work is being carried out from engineered temporary piling platforms built using the recycled material from the original Romsey Road bridge.

Over 150m³ of concrete has now been poured onto the deck to transform the new 48metres of steel structure into a bridge.  This work has taken place off line in our compound adjacent to the motorway to minimise disruption to the travelling public.

A whopping 28 lorry loads of concrete came in quick succession to the site to enable this successful pour to take place.

We are currently working on the construction of the cantilevered parapets which, once poured and cured will enable the bridge to be transported into its final location.  The bridge will then be connected to the newly built abutment structures ready for waterproofing and the final road surface so that it is ready for vehicular use.

Matt Whale Senior Site Manager said “After a very challenging couple of months dealing with poor ground conditions and complex temporary works designs, the bridge deck pour is a great project milestone to complete, the operation completed smoothly and sets the team up nicely for the next installation closure date.”

Last year, the M27 reopened 16 hours ahead of schedule after work was carried out on junctions 3 and 4.

This followed a weekend closure of the M27, last year where Osborne, along side supply chain partners demolished the western half of the Romsey Road Bridge.

The next weekend closure, to install the new bridge deck, will be between 28 – 30 June 2019.
