The Government has awarded Carillion a £105m contract to manage part of the M6 motorway.
It will work on the Birmingham section, imposing variable speed limits and opening up the hard shoulder to traffic in an attempt to alleviate bottlenecks and improve safety and journey times.
The contract will kick off at the end of this month, with completion scheduled for 2014-15.
Carillion has previously won two other contracts to manage the motorway around Birmingham, and Caroline de La Soujeole, support services analyst at Seymour Pierce, said that the new deal was "small but noteworthy".
"It shows that contract activity in the UK support services arena remains sustained," she added.
