Plans include new car park, cycle facilities and improved bus interchange.
Weston-super-Mare £16 million infrastructure improvements to Junction 21 of the M25 and other parts of the road network has been given initial Government approval.
The scheme would reduce queuing to get onto the motorway and address the congestion problems around the junction.
The scheme also includes improvements to the A370 to better link the town centre with the rest of the town and major upgrade of facilities at Worle Railway Station, including a new car park, cycle facilities on the south side of the station, improved bus interchange, and better facilities on the platforms for passengers.
New or extended bus services will also now call at the station with improved bus priority.
Transport Minister Paul Clark said: “Over the next few years Weston-super-Mare is going to benefit from major changes and it’s vital we make access a priority with so many more residents, commuters and businesses expected in to the area."
