The Circumferential Road 5–Kalayaan Avenue Interchange, also known as the C-5–Kalayaan Interchange, is a road interchange in Makati, Metro Manila, the Philippines. Originally a regular four-way intersection between Circumferential Road 5 (C-5) and Kalayaan Avenue, it was fitted in 2009 with the country's first elevated U-turn slots, built in an attempt to speed up traffic along the C-5 corridor. ==History== The C-5–Kalayaan intersection is the last major intersection of C-5 south of the Pasig River, and traffic congestion in the area is very heavy, even extending to as far north as Ortigas Avenue during rush hour. This ultimately led both the Metropolitan Manila Development Authority (MMDA) and the Department of Public Works and Highways (DPWH) to conclude that the construction of an interchange between the two roads was needed to speed up traffic. However, both agencies disagreed on the final design of the interchange. While the DPWH sought to construct a , six-lane underpass to divert through traffic under the intersection, the MMDA claimed that this was too expensive and impractical, and sought to build elevated U-turn slots instead, which it also argued would not require other infrastructure, such as street lamps and anti-flood measures, unlike an underpass.〔 In the end, the DPWH's proposal, which would have cost ₱600 million, was abandoned in favor of the MMDA's proposal, which was half the cost. Construction of the interchange, funded by a Japanese loan package,〔 began in April 2008, when work began on the southern elevated U-turn slot, which was completed six months later. The northern elevated U-turn slot, meanwhile, began construction on December 2, 2008, and was completed on April 17, 2009. During construction, traffic that would normally cross the C-5–Kalayaan intersection was diverted through Circumferential Road 3 (C-3), including Gregorio Araneta Avenue, and Epifanio de los Santos Avenue (EDSA).〔 The entire interchange was inaugurated by President Gloria Macapagal-Arroyo, accompanied by MMDA Chairman Bayani Fernando, on May 5, 2009, and it was opened to traffic the next day.〔
