Three major road improvement schemes in Hull and North Lincolnshire have taken a step forward with the government pledging £331m for the projects.
Transport minister Sadiq Khan announced funding to widen the A160 as well as improvement plans for the A63 in Hull and the A18-A180 link road.
The projects will improve access to the Port of Immingham and reduce congestion in Hull.
Mr Khan said the plans would make journey times more reliable.
The A160 scheme, which includes plans to upgrade it into a dual carriageway, will cost about £110m and is due to completed by 2015.
Eight options were considered for the preferred route, with the chosen one being announced by Mr Khan earlier on Monday.
This option includes a new road bridge linking the two halves of Town Street and moving Ulceby roundabout closer to Harbrough roundabout.
Improvements to the A63 will upgrade a one mile (1.5km) section of the A63 Castle Street in Hull, giving better access to the Port of Hull and reducing congestion in the city.
Mr Khan also announced the preferred route for the A63 scheme, which includes widening of the eastbound carriageway to three lanes and better access for road users and pedestrians.
The government has also approved the first phase of plans for a scheme to link the A18 to the A180.
Councillors and businesses welcomed the announcement.
Richard Kendall, policy executive at Hull and Humber Chamber of Commerce, said: "These are major schemes that are vital to our region's competitiveness.
"Improving access to the Ports of Hull and Immingham will help to secure their status as major ports and unlock further investment, which will lead to thousands of jobs being created."
Councillor Mark Kirk, leader of North Lincolnshire Council, said"This represents massive confidence in North Lincolnshire and underlines our critical place in both the national and global economy."
