The Ministry of Works and Transport (MOWT) has developed a programme to examine the operations of the interchange between Uriah Butler Highway (UBH) and Churchill Roosevelt Highway (CRH). Originally, this interchange, operating as the main East/West to North/South connection functioned poorly due to the level of traffic and the inability of the existing roadway geometries and signalization to handle the traffic volumes experienced at this location. To provide a solution to the traffic congestion issues, the MOWT examined the traffic conditions, geometries and other relevant aspects of the intersection and created a plan to resolve the traffic constraints. This resulted in the implementation of several packages to systematically alleviate these issues.

The first package, Package A, involved expanding the San Juan River to hold 3 lanes of traffic in each direction to provide additional capacity for traffic along CRH. The second package, Package B, involved the construction of a flyover ramp to allow free flow traffic for vehicles travelling eastbound on CRH to southbound UBH. As part of completing the overall improvement of the UBH/CRH interchange, a re-examination of the design for a grade separated interchange allowing for the UBH to pass over CRH and several connecting ramps was performed accounting for new traffic movements and access requirements.

Package A
Package A was completed adding an additional three (3) lane bypass, around the right turn lanes and was undertaken together with the construction of a bridge over the San Juan River.

Package B
On May 1st 2009, Package B, an 18-metre high & 600-metre long bridge over the CRH/UBH Intersection that runs from the vicinity of the San Juan River Bridge to Grand Bazaar was opened. The height of the bridge facilitates the separation of the East-West and North-Bound sections of the Interchange.

Package B also included the construction of a West to South ramp, a New Diamond interchange and service roads at the Bamboo intersection. All of which are contributing factors in alleviating the traffic congestion East- West and North South routes.

Package C
Package C consists of the construction of a North to South Bridge that is located in the vicinity, south of the Churchill Roosevelt Highway / Uriah Butler Highway (CRH/UBH) Intersection. The design removes the major UBH north/south link across CRH and continues to provide service by means of an overpass. The design maintains access to Grand Bazaar Mall by an exit ramp onto a service road off of Westbound CRH and a connection to the UBH overpass accessible for traffic approaching from all directions.
