Four Years after the completion of the expansion works to the Gros Islet Highway, there appears to be very little relief to drivers who live up North in their journeys into Castries. We have four lanes now and already it seems to be insufficient. Some have been making calls for six lanes to be built. I believe that we have to think out of the box and look at the latest research in Transportation Engineering to come up with solutions. St. Lucia cannot afford such expansions of six lanes in the North corridor, as further expansion would result in significant land and property acquisition costs. These acquisition costs alone can run into the billions. This is why we have to be creative in the limited fiscal space small islands like St. Lucia are placed. Transportation Engineering has now been influenced by theories in Physics, and the flow of traffic has been modelled along the flow of...
