The Ministry of Works and Infrastructure (MOWI) of Trinidad and Tobago undertook a project to alleviate traffic congestion at one of the country’s most important highway intersections - that between the Churchill Roosevelt Highway (CRH) and the Uriah Butler Highway (UBH). The project included an 18-meter high, 600-meter long bridge over the CRH/UBH intersection, connecting the San Juan River Bridge to Grand Bazaar. By providing a separate route across the junction, the new bridge reduces the amount of traffic using the junction, and thus the congestion at this key point on the two major highways.
Six expansion joints were required for the total of three new bridges constructed. Considering especially the relatively high transverse movements to be accommodated, mageba modular expansion joints were selected, due to their exceptional flexibility. The two joints of the main bridge are of type LR4 (with four gaps), accommodating longitudinal movements of +/-160 mm and transverse movements of +/- 83 mm, while the four joints required by the other two structures facilitate longitudinal and transverse movements of +/-100 mm and +/-68 mm respectively.
