The A14 road near Kettering is to be improved
Four transport schemes linked to new housing in Northamptonshire have been shortlisted to receive up to £17.6m from the government.
The county council is bidding for cash to improve a bus route between Northampton and Wellingborough.
Northampton Borough Council wants to improve routes from the town centre and improve safety measures at Sandy Lane.
The Highways Agency wants money to control traffic levels from slip roads onto the A14 at Kettering.
Communities minister Caroline Flint said: "One of the main priorities this government faces is building the new homes that families and first time buyers, in particular, so badly need.
"We are looking to support that development by getting the right infrastructure in place.
"The schemes shortlisted for the next stage in bidding for funding have shown they can help unlock potential in proposed new developments, as well as provide the transport infrastructure to support growing communities and improve access to town centres and jobs."
Transport minister Rosie Winterton said: "This funding plays a critical role in supporting local authorities to ensure housing developments are properly planned, with high quality infrastructure at the centre.
"Almost half of the investment will go to schemes that reduce the reliance on cars and encourage more sustainable travel.
"This presents real support to new communities with genuine ambitions for changing the way they travel."
