The Highways Agency has published a construction timetable for the 14 major road schemes worth £1.4bn due to start on site by 2015.
Work will start on improvements to the M62 in West Yorkshire, the M4/M5 around Bristol and on the A23 in West Sussex in the next 12 months.
A further three schemes – on the M1 near Sheffield, M6 around Birmingham and A11 in Norfolk - will start in the financial year 2012-2013.
Roads Minister Mike Penning said: “These schemes will deliver vital investment across the strategic road network, driving economic growth and boosting the UK economy.
"For every pound invested on these schemes on average we will get back £7 of benefits to the economy with some delivering even higher returns."
The schemes will be built using the Agency's target of reducing the cost of capital major projects by 20% against original estimates.
