The average speed of vehicles travelling through the tunnels is now monitored by SPECS speed cameras. From the outset a tunnel was built rather than a cutting being dug to avoid spoiling an area of outstanding natural beauty and a Site of Special Scientific Interest, much of which is owned by the National Trust. Before digging started an environmental survey was carried out. Common lizards, adders and slow-worms found at Boundless Valley were relocated to National Trust land at Highcombe Edge while grass title: Lincoln Tunnel text: were 19,039,210 tolls collected in the eastbound direction. Although the center tube normally provides one travel lane in each direction, both of the travel lanes in the tunnel's center tube are reversible and can be configured for peak-hour traffic demand if needed. The northern and southern tubes respectively carry westbound and eastbound traffic exclusively. Normally, only motor traffic uses the tunnel, but every year, a few bicycle tours and foot races pass through by special arrangement. Each tube provides a roadway with two lanes and of vertical clearance. Most vehicles carrying hazmats are not allowed in the tunnel, and trucks title: Bankhead Tunnel text: designed in the Art Deco style that was popular during the time of construction.

Originally that whole area was covered by the Burgate Beds, but when the Weald was uplifted, the Burgate Beds were eroded away. Most of the tunnel passes through the Upper Hythe C and D layers and the Lower Hythe A layer which are described as "Weak, locally very weak to moderately strong, slightly clayey fine to medium sandstone with occasional thin beds of clayey/silty fine sand" and typically has Uniaxial Compressive Strength (UCS) values of 2–5 MPa. The rock is heavily fractured and has mean fracture centres varying from . The southern end of the tunnel
