Because of this, a new four-lane diversion road and tunnel section was planned. The new runway tunnel will reduce delays and tailbacks caused by aircraft taking off and landing. Construction of the new road was due to begin in January 2008 and be completed by the beginning of 2009, but as of 2016 it remained incomplete. Although the road across the runway is to remain in place, for exceptional, specific, or emergency use, it will not be available for routine day-to-day use by private vehicular traffic. Pedestrians will not be required to travel via the new road/tunnel, and will continue to cross the runway at the present location. A prolonged litigation between the Government of Gibraltar and contractor OHL over the delay was resolved in June 2016 with an agreement for OHL to complete the works at a price of £24 million and a projected finish date of November 2018. The most recent estimate for completion of the project is by the end of the first half of 2021.
