Roadway Improvements Design



Road improvements include changes to roadway horizontal and vertical alignments, geometrics or physical improvements involving widening, incorporating intersections and roadside traffic safety features, as well as restoration and rehabilitation including surface repaving, repair or replacement of stream crossings, rehabilitation or replacement of drainage and bridge structures.
