The ABC Highway is the main urban highway in Barbados. Opened in 1989, it is named after three famous Barbadian politicians: John Michael Geoffrey Manningham ("Tom") Adams, Errol Barrow, and Hugh Gordon Cummins. From the east, the highway stretches from the Grantley Adams International Airport in Christ Church, to the western end at Cave Hill Road and University Drive, Cave Hill Campus, University of the West Indies, in Saint Michael. It roughly encircles the Parish of Saint Michael and the wider metropolitan area of Bridgetown. Route description The highway consists of two-lane and dual carriageway sections with at-grade intersections, mostly roundabouts. A 2006–2007 expansion project enlarged some areas, and there was some public sentiment voiced in local media about the project's lack of a competitive tender process or studies to justify costs. The construction and widening of the ABC Highway from the Darcy Scott Roundabout in Warrens, St. Michael to the Garfield Sobers Roundabout in Bartletts, Christ Church was started on 24 July 2006 with two local construction companies, Rayside Construction and C.O. Williams Construction, when they removed the old streetlights and the old traffic lights at the junctions of the ABC Highway and Pine East-West Boulevard, Upton Road at BET Hill on Highway R and Highway 6; constructed jersey barriers in the center with the installation of the new HPS streetlights on the highway; constructed the new roundabouts like the Samuel Jackman Prescod and Darcy Scott Roundabouts in Warrens and the Pine, St. Michael. The Greater Warrens Traffic Improvement Project was started from late December 2010 into early January 2011 to mid-December 2014 with construction and widening of Jackson Road on Highway 2 to the newly constructed Jackson Roundabout around the Baobab Tree and Lodge Hill, St. Michael, two Warrens Mini Roundabouts in Warrens, St. Michael and the Welches and Redmans Village Roundabouts in St. Thomas. On 27 April 2008, during its effect, they changed the junctions from a two-way street into a one-way street with the Wildey "Y" Junction of Upton Road on Highway R, the ABC Highway and Highway 6. There was also a footbridge construction at the Pine, St. Michael, from early September to late November 2012. They had also installed two new traffic lights; one at the pedestrian crossing at Mount Friendship, St. Michael, and another at Redman's Village, St. Thomas. The construction of the four-lane highway was finished by 31 August 2009. Also, the
