If given the go-ahead the vast infrastructure project would rank as the most ambitious road scheme since the construction of the first motorways 50 years ago.
The Trans-Pennine tunnel study was launched by the government last year, one of a number of studies to establish the government’s next phase of road improvements, which will get underway from 2020.
Today’s interim report shows the continued strong case for the tunnel which could provide safer, faster and more reliable journeys for motorists.
The tunnel between Manchester and Sheffield could be a national first and almost halve journey times between the two cities.
All five routes join the M60 east of Manchester to the M1 north of Sheffield, with four options starting at the M67.
Three corridors A, B and C are being recommended for further detailed study because they offer greater use of existing surface infrastructure and greater practical feasibility with shorter tunnel lengths.

Across these three key corridors there are around a dozen route option with tunnels ranging from 10 miles to 18 miles.
The link would help protect the environment by reducing traffic through the Peak District National Park and support the government’s plan to build a Northern Powerhouse.
Transport Minister John Hayes said: “I want people in the north of England to benefit from quicker, more reliable journeys.
“We are already spending £15bn on the biggest upgrade to the road network for generations.
“This next phase is aimed at creating more vital links, creating jobs and opportunities and helping hardworking families across the country feel the benefits of our investment.”
John Cridland, Chairman of Transport for the North, said: “This is just one of the visionary projects Transport for the North is working on, as well as other schemes, such as Northern Powerhouse Rail, as we continue to develop a Transport & Investment Strategy to connect the North and transform its economy.
In the final stage of the study, due to be completed by the end of the year, the strategic and economic cases for each option will be assessed and cost estimates will be provided.
Two further reports – the A1 east of England and the Cambridge to Oxford expressway – were also published today.
Studies into the M25 south west quadrant, the Manchester north west quadrant and the Northern Trans-Pennine are also underway.
