The bridge, in Newsham, will carry South Newsham Road (the A1061) over the tracks.
Once the flyover is completed, the level crossing on the road will be removed. It is hoped this will reduce congestion in the area.
Funding for the construction of the bridge was approved by Northumberland County Council’s cabinet in April, which council leader Glen Sanderson said would “help Blyth to continue to grow economically.”
The track is set to get busier from next year as passenger services return between Ashington, Blyth, and Newcastle as part of the Northumberland Line project.
Passenger trains have not travelled on the line since 1964, when the line was closed as part of the Beeching cuts.
Trains will stop at new stations in Ashington, Bedlington, Blyth Bebside, Newsham, Seaton Delaval, Northumberland Park, and Newcastle when the project is finished, currently scheduled for August 2024.
