Ministers have approved the long-awaited Lincoln eastern bypass with work due to start in May or June.
It should mean that drivers setting their journey planner to the city suffer fewer traffic jams.
Richard Davies, a Lincolnshire county councillor, says the new road will significantly reduce congestion in Pelham Bridge, Canwick Hill and other traditional traffic hotspots.
The planned £96 million single carriageway will link Wragby Road roundabout on the A158 to a new Sleaford Road roundabout on the city's A15.
The whole bypass debate has split Lincoln with opinion divided and campaigners forming groups against and for the scheme.
Last August's inquiry put the case before an inspector from the Department for Transport (DfT).
They analysed whether or not side road and compulsory purchase orders (CPOs) were required for bypass work to go ahead.
Lincolnshire county councillors approved the scheme in summer 2013.
DfT officials then froze the plan after fears concerning a junction linking a footbridge with Hawthorn Road.
County councillors gave the go-ahead to the footbridge's amended design and a further public inquiry was held last year.
Cllr Davies called the Government approval "great news".
