In April 2018, Mary, our tunnel boring machine (TBM), set off from Goxhill on her ground breaking journey beneath the River Humber to construct the tunnel for our replacement gas pipeline.
She reached the other side of the Humber, at the village of Paull, in September 2019.
Work is now underway to install the replacement gas pipeline inside the tunnel.
Our tracker below will help you stay updated on Mary’s progress and the key construction stats from the project.
