Info

It should be noted that growth and development has occurred since the AADT data was collected in 2005. Even more significant than city growth, the oil industry has experienced a resurgence in western North Dakota since 2005, which has dramatically increased area-wide traffic volumes related to drilling, transporting of crude oil, influx of related businesses, and the personnel needed to carry out this economic and business activity. As traffic volumes increase, additional roadways are likely to approach their capacity thresholds and experience congestion. Continuity and Connectivity Continuity of routes within the city is an issue, due to the presence of several large natural and man-made features which serve as barriers to cross-city travel. The City of Williston is bordered by the Little Muddy River to the east and the Missouri River to the south. The topography of the area further limits the street system as the city is bordered by large hills with prohibitive slopes to the east and west. In addition, several man-made barriers limit the transportation system. These include the Sloulin Field International Airport on the north side of the city, US Highway 2/85, which bisects the city, and the BNSF Railway tracks at the south end of the city. Sensitivity to these features is important and has played a large role in the development of the street system. Figure 9 illustrates some of the factors limiting the continuity and connectivity of the roadway network within the City of Williston. In the core area of the city, bounded by 26th Street East, the Little Muddy River, the railroad tracks, and West Dakota Parkway, continuity is excellent, consisting primarily of a traditional grid pattern of streets and blocks. There are few connectivity issues in this portion of the city. Beyond these boundaries, traffic flow is hampered by a lack of continuity in some areas. There are few convenient east/west routes crossing US Highway 2/85, and as development continues to the west there is an increasing need for crossings of US Highway 2/85. In addition, there is little connectivity to the east of the city as there is only one easily accessed roadway which crosses the Little Muddy River (ND State Highway 1804). One other corridor, 54th Street NW, crosses the river north of city limits, but the current roadway network does not facilitate access to this river crossing, and the city’s development pattern makes it inconvenient for most residents and businesses. Finally, US Highway 85 provides the only Missouri River crossing in the area. Connectivity and continuity of roadways within the city is an issue that will persist as the city continues to grow into areas where topography, rivers, the airport, and US Highway 2/85 are barriers to connectivity. Features such as steep topography and natural drainage corridors, such as the Sand Creek, are not only ecologically and geologically sensitive features through which to construct roads; they also make road construction more costly. Despite these features, it is important to provide accessibility, mobility, and efficiency within Williston’s transportation system. Safety Roadway safety is a central concern of transportation professionals and the public, and a key issue in this Transportation Plan. NDDOT maintains a database which includes crash records from roadways across the state of North Dakota. These records identify the location and circumstances associated with each crash. This dataset was reviewed to identify the location of crashes in the City of Williston for the time period from July 1, 2005 to June 30, 2008. In total, there were 773 crashes, of which zero involved fatalities, 133 involved personal injury and 640 involved property damage only. In general these crashes were widely distributed throughout the Williston Transportation Plan 16 August 2010
city, with most locations accounting for only one or two crashes. This suggests that many crashes were random occurrences. However, there were higher concentrations of crashes at select locations. These high crash locations are listed in Table 2 and illustrated in Figure 10. It should be noted that there is a correlation between the frequency of crashes and traffic volumes. Roadways with higher traffic volumes are expected to have more total crashes than lower volume roadways. The highest concentration of crashes within the city occurred along the 2nd Avenue West corridor, especially from 26th Street to 11th Street. The locations along this corridor with the highest frequency of crashes include the intersections with 26th Street, 18th Street, 14th Street, and 11th Street, all of which had more than 20 crashes in the three-year study period. Based on this safety analysis, further investigation is warranted in order to identify potential safety improvements along the 2nd Avenue West corridor. In addition, a high concentration of crashes occurred at the intersections along the Dakota Parkway West (US Highway 2/85) corridor. A detailed safety analysis, as well as recommendations to improve safety, were prepared as part of the Highway 2 (Dakota Parkway) Corridor Study available for review from the City of Williston or NDDOT.
