Executive Summary Nevada Department of Transportation (NDOT) Safety Engineering authorized a Complete Streets- Focused Road Safety Assessment (RSA) to be conducted on US 50, between Stateline NV and the intersection of SR 28. (See Study Corridor Vicinity Map on page 2.) This involved reviewing existing conditions and data and performing a field review. There have been previous RSA’s conducted on this corridor. This specific RSA was initiated by the design team prior to construction of an upcoming project to convert this corridor into a “Complete Street”. A complete street is designed to offer improved roadway usage to all users including motorists, motorcyclists, transit, bicyclists, and pedestrians. Per meetings with NDOT Safety, it was stated that the design team will look at all methods of obtaining a complete street, such as road diets/reconfiguration and road widening. The purpose of this RSA is to identify potential road safety issues that currently exist and that could be considered when converted to a complete street layout and suggest countermeasures to mitigate those safety issues in future projects along the studied corridor. The studied segment, shown in the map in photo 1 on page 2, is 12.30 miles long and has a right-of- way ranging from 30-200 ft from the centerline, from milepost (MP) DO 0.00 to MP DO 12.30. The current roadway geometry consists of two general purpose lanes in each direction with left turn lanes at select locations. The speed limit varies from 25 mph to 50 mph. Primary suggestions include providing ADA compliant facilities, facilitating left turns, improving safety for pedestrians at the crosswalk on SR 207 (also known as Kingsbury Grade), addressing on street parking, and providing bicycle facilities. A summary of the suggestions is listed on page 47. RSA on US 50 from Stateline to SR 28 Page 1 End RSA at SR 28. Begin RSA at Stateline.
