The 1.2-mile stretch will connect Burnetts Lane to Allington Lane. The council said new features include shared footways, cycle routes as well as future bus connections and additional trees.
The project forms part of the One Horton Heath development, with a budget of more than £485 million, which is set to see 2,850 homes built in the region.
It is understood that the new link road connecting Hedge End to Fair Oak will be named The Avenue and is set to open this spring.
EBC said The Avenue includes five bridges, three linked with the road and two for pedestrians and cyclists.
The road was first built to not only connect the new homes as part of the development but also help with local traffic flow and construction traffic during the project.
Those travelling along the new road will be able to enjoy 10 kilometres (6.2 miles) of cycleway and footpaths connecting people to the surrounding areas, as well as future schools and facilities.

A spokesperson for Eastleigh Borough Council said: “During construction, 16,500 cubic meters of earth was excavated and repurposed on-site – a volume 53 times the height of London’s Shard.
“This cut down lorry trips and reduced the environmental footprint.
“The road also boasts sustainable drainage systems with ponds and natural methods to manage rainfall, control surface water, and reduce flooding risks – a win for the environment and the community.
“Luddon Construction is adding the finishing touches to ensure this new link road is safe, efficient, and ready for all users.
“The plan is to complete the work by early March and open after any remedial work is completed, which could be a couple of weeks.”
EBC has previously stated that 35 per cent of the homes will be affordable, socially rented, and shared ownership homes, while 33 per cent will be available for market rent.
