PINS announced the news last week, after government-owned roads company Highways England submitted the DCO application last month.
The scheme proposes the widening of the A1 in Tyne and Wear to four lanes between junction 65 and 67 on the southbound carriageway and three lanes on the northbound carriageway to provide additional capacity.
The scheme would also include the replacement of a railway bridge at Junction 67.
Highways England says that section of the A1 "suffers congestion" and "traffic is also expected to grow with new housing and employment developments planned for the area. Road improvements are needed to support this growth."
Last month, plans were approved for works to assist in the delivery of a new link road on the border between two West Midlands council areas, after planners advised that the scheme would 'unlock' an employment area for future development and provide wider regeneration opportunities.
Also in August, Planning reported that a new administration at Herefordshire Council had decided to review plans for the Hereford Bypass partly over climate change concerns, despite warnings from officers that the move risks the proposed delivery of more than 3,000 new homes.
