More than £24m is to be invested in road schemes across Essex to help meet the expansion plans for the county.
The government has announced £11.2m funding for a new junction on the A12 near the Community Stadium, Colchester.
While £9.9m is going towards the dualling of the A414 between Chelmsford and Harlow near the M11.
The government also announced a £3.6m grant to improve public transport and cycle ways in and around Harlow - which is due to grow by 16,000 homes.
The schemes are due to be completed by March 2011.
Councillor Norman Hume, cabinet member for highways, said: "This is absolutely fantastic news for Essex and represents a huge vote of confidence in the work we are doing to improve the quality of life of our residents.
"Many thousands of our residents will benefit from these schemes through reduced congestion and better and more sustainable access.
"We will be using this money to deliver these much needed improvements with all of these schemes to be completed by Essex County Council just two years from now which will represent a major achievement."
Councillor Andrew Johnson, leader of Harlow Council: "The A414 dualling scheme is crucial for Harlow.
"We fully back this project which will bring huge benefits in terms of our economy and relieving the misery of congestion which affects so many people every day."
