There was cheer for motorists as Junction 10a was formally opened today.
The ceremony was attended by Andrew Jones MP, Parliamentary Under Secretary of State for Transport, who officially cut the ribbon for the new improvements scheme.
It is already judged that the £30 million scheme has reduced congestion and improved journey times for motorists.
Cllr Sian Timoney, portfolio holder for regeneration, said: “The improvements will unlock around £800 million of development covering housing, employment and retail growth throughout the south and east of Luton.
“The total increase in the number of jobs available once these sites are developed is expected to be in the region of 15,000 over the next 15 years.”
Speaking at the opening, Transport Minister Andrew Jones said: “This scheme will make it easier for people to access Luton Airport and the M1, providing better journeys for residents and businesses and supporting more housing and jobs.”
The cost of the £30million scheme was met by Government funding totalling £25.8 million. The balance was achieved through a combination of Council capital funding and local third party contributions.
