Specialist road safety barriers aid Gloucestershire bridge repair project
Complex essential repair work on three Gloucestershire motorway bridges was made possible with the help of specialist road safety barriers.
Specialist temporary vehicle restraint systems (TVRS) were installed to protect the bridges, located east and westbound on the M50 motorway, while the intricate repair work was carried out.
The extensive two-year project, which was only recently completed, involved replacing the bearings and the parapet railings on the top of the motorway bridges.
Leading VRS specialists, Hardstaff Barriers, installed barrier systems to protect the temporary structures that were installed to prop up the bridges during the repair project.
The very high containment H4a TVR, Maxibloc, designed even to restrain the impact of a 30-tonne lorry travelling at 65 km/h, was deployed in the higher risk areas.
The surface-mounted Multibloc barrier, which provides N2 containment, was used in the lower risk areas of the site.
Hardstaff Barriers installed the Rebloc RB 80 barrier for the parapet works on the top of the structures, providing a narrow footprint of just 300mm, a working width of W1 and N2 protection for tight work areas.
Charlie Crawford, of contractor Golden Orb, who was part of the bridge repair project said: “We needed specialist TVRS for a very complex scheme.
“Working on top of the three structures brought a number of interesting challenges, which, working together, made the site safe with the correct TVRS.
“The Hardstaff team were very pleasant and very cooperative, always doing their best to deliver at short notice.”
