Dorothea Dix Park is located near Downtown Raleigh, a rapidly growing metropolitan area. Planning for Dix Park includes planning for how people will access the park. The following analysis outlines the recommended changes to the surrounding street network to serve the park and its visitors.

Discovery Transportation Summary

Transportation access to and circulation within the Dorothea Dix Park site has adapted to its evolving functions.Transportation Today, the transportation Summary network is singularly focused on automobile access, channeling vehicles to sparse entrances to the site. Internal streets were built to connect the former hospital campus to outbuildings occupied by North Carolina Department of Health and Human Services offices. The streets are narrow and designed for low traffic volumes. The Rocky Branch Greenway along Western Boulevard is the only formal bicycle path accommodation on the site, and sidewalks between buildings are the extent of the site’s formal pedestrian accommodations. However, people enjoy walking and bicycling on the low traffic streets. Access to the site was historically limited because the site was not a public destination and purposely secluded from adjoining properties and neighborhoods. As such, roadways bordering Dix Park were designed to accommodate regional traffic. These multilane roadways are barriers to connections with nearby neighborhoods and parks. Entrances onto Dix Park are designed to discourage and restrict direct access. There are no direct connections between the Dix Park site and the State Farmer’s Market. The Dix Park Plan will describe another evolution in the site’s future transportation network. Access to neighboring properties will be opened. Bicycling, transit, and walking will be critical travel modes for accessing the park. In pursuit of these goals, this memo examines the current conditions of the transportation network on and adjoining the site. It considers the priority issues and obstacles to visitors safely and comfortably travelling to and through this premier destination, while minimizing the need to drive or park a vehicle.

Cyclists and pedestrians need safer access to the Dix Park site Cycling and walking near the Dix Park site is currently limited to neighborhood streets severed from the site by major roadways and part of a local greenway. Western Boulevard and Lake Wheeler Road are the most significant barriers to bicycle and pedestrian access to Dix Park. There are no formal bicycle or pedestrian accommodations at entrances along Lake Wheeler Road. Pedestrians and cyclists cross Western Boulevard at Boylan Avenue, Hunt Drive, and Ashe Avenue, but the crossings are neither intuitive nor convenient. The Boylan Street pedestrian crossing is intimidating and requires that pedestrians and cyclists cross in two stages. Cyclists can more easily access Dix Park from the west, crossing Centennial Parkway at the Blair Drive entrance, but this entrance also lacks formal pedestrian and bicycle accommodations. The Rocky Branch Trail enters the site from the west as a shared use path parallel to Western Boulevard. The path also extends across South Saunders Street east of the Dix Park site.

Walking and bicycle paths through Dix Park should create direct and connected routes to regional destinations On the Dix site, the Centennial Bikeway Connector greenway (along Centennial Parkway) and the Rocky Branch Trail (parallel to Western Boulevard on the south side) are the only formal bicycle paths or extensive walking accommodations on the Dix Park site. Existing sections of the Rocky Branch Trail are in major disrepair and do not provide safe or accessible crossings across Western Boulevard to Pullen Park, North Carolina State University (NCSU) Main Campus, or the Boylan Heights neighborhood.
