| 摘要： | This report provides a safety evaluation of the installation of concrete barrier, median striping, rumble strip, roadway widening, and implementing enhanced enforcement program on State Route 37 (SR-37) between the intersection of Route 121 in Sonoma County and the Napa River (Mare Island) Bridge in Solano County. The project eliminated existing passing lanes, and replaced them with concrete barrier, two 4 to 5-foot inside shoulders, a 12-foot lane in each direction, and 8-foot outside shoulders. The construction improvements on SR-37 resulted in a two-lane conventional highway separated by Type 50 concrete barrier. The improvements were not intended to increase the capacity of the highway, but to reduce to eliminate head on collisions. The improvement project was developed to be implemented in three phases. Phase I and II have been completed. |
