- W763043238 abstract "The 25-km dirt road in the Dominican Republic's mountainous central region from Jarabaca to Constanza, a lifeline for local farmers transporting their goods, suffered from landslides and severe erosion. The often narrow roadway lacked appropriate lighting, proper drainage and safety barriers. Originally developed in the 1950s, sharp curves, hazardous road conditions, and topographical changes made the road extremely dangerous. Landslides, the result of poorly designed and constructed sideslopes, caused frequent closing of the road that resulted in havoc for locals and daily travelers. A project to improve the road, which was long overdue for repair, began in February. Its goals were to reduce transport time and cost as well as facilitate access to the area's tourist destinations. The road runs through the island's largest mountain chain, so there was no flat ground on which to build. Because the previous retaining walls were poorly engineered, the slopes were exposed to severe erosion. New retaining walls were considered to replace the previous ones and create space for a two-lane road, reduce erosion, and improve vegetation. Rain was a constant challenge, but construction of the $1 million project was subjected to strict deadlines and had to remain on schedule, even though the work was stopped several times a day to allow agricultural and commercial traffic. The team completed its goal by more than 50%. It now takes 30 minutes rather than an hour or more to travel the entire stretch of the road. The road has also seen an increase of traffic--from about five vehicles per hour before construction to more than 30 vehicles per hour. In addition to improving the lives of the locals, the road also provides a safer and healthier environment." @default.
