A brand new junction costing an enormous £290million might make a significant distinction to a busy UK motorway. Hampshire’s busiest motorway interchange has made progress after contractors lifted two 48 metre metal bridge beams into place. The work came about throughout deliberate weekend closures on the M3.
The M3 Junction 9 enchancment scheme goals to alleviate power congestion on the junction the place the M3 meets the A34 close to Winchester. Groups put in the northern and southern gyratory bridge beams in February, marking a big second in development. Principal contractor VolkerFitzpatrick is working with Balfour Beatty as VFBB for Nationwide Highways.
It used a 750-tonne crane to position the 2 roughly 100-tonne beams on new abutments as a part of the realigned junction construction.
The beams will type the decks of two new bridges wanted for a redesign that replaces the present sign‑managed, single giant roundabout with a “dumbbell” structure.
It will embrace two smaller, linked roundabouts related by bridges to permit free‑stream motion.
The change ought to cut back the necessity for visitors to cease and so will ease delays at peak instances; the junction presently handles greater than 6,000 autos an hour within the busiest durations.
It took contractors two weekends to finish the work, which was described as difficult.
The upgrades are being funded by the central Authorities.
The work will widen the M3 to 4 lanes by way of the junction, create free‑stream hyperlinks between the M3 and A34, and embrace amenities for pedestrians, cyclists and horse riders.
The transfer will assist native growth and regional freight motion, in keeping with Nationwide Highways and VFBB, reviews New Civil Engineer.
“I’m extremely pleased with everybody concerned. This achievement brings us one other step nearer to delivering a junction that can considerably enhance journeys, strengthen the regional community, and supply lengthy‑lasting advantages for street customers and native communities.”
Completion is anticipated in summer season 2028.
