Loop 286 at Spur 139 Crossover Removal Narrative The proposed safety enhancement at this location consists of removing the existing crossover.. This corridor has an ADT of 27,202 vehicles per day. The estimated cost for this work is $29Q,327.40. The Safety Improvement Index (cost benefit ratio) of this project is 13.63. Some potential benefits of this enhancement include: improving traffic safety, increasing through capacity and reducing delays. From 2017 through 2019, 3 accidents have occurred resulting in 3 non -incapacitating injuries due to utilization of this crossover. Other accidents such rear end collisions caused by vehicles slowing down to utilize the crossover and other related accidents are not included in the previously noted data. Because of this, it is reasonable to assume that many additional accidents could have likely been prevented had the crossover been removed. Removal of the crossover would require vehicles to utilize the following crossovers to cross Loop 286. Northeast bound traffic would utilize the Stillhouse Road underpass as a crossover, which would result in an increased round trip travel distance of 2.88 miles. Southwest bound traffic would utilize the FM 195 underpass as a crossover, which would result in an increased round trip travel distance of 1.66 miles.
