INTERNATIONAL BOULEVARD CASE STUDY OF ACCESS MANAGEMENT IMPLEMENTATION

Access management measures were part of a comprehensive design solution for a 1.1-mile section of International Boulevard, a major north/south arterial serving both local and regional traffic within the City of SeaTac, Washington. International Boulevard, which is a portion of SR 99, provides a regional link between cities in the Puget Sound Region and a major route to Sea-Tac International Airport. Prior to reconstruction, the roadway was five lanes (including a center, two-way left-turn lane) with paved shoulders, intermittent sidewalks, and unrestricted access to and from adjacent properties. Traffic volumes ranged from 32 to 42 thousand vehicles per day. The existing land uses along the boulevard include some of the Puget Sound Region's largest motels, Sea-Tac International Airport, office buildings, and other retail uses. International Boulevard had suffered from significant traffic congestion, high traffic accident rates, and unsafe pedestrian conditions. The City's objectives for the reconstruction project have included improving traffic and pedestrian circulation, supporting transit use, and aesthetic enhancements. The design included reconstruction consisting of access management measures (including conversion of two-way left-turn lanes to a median, and driveway reductions and consolidations), a high-occupancy lane, an arterial signal control system with area-wide integration, transit signal priority, pedestrian amenities, transit stop and rider amenity improvements, landscaping, illumination, and undergrounding of overhead utilities. This paper presents a case study on how the project was developed and, in particular, how access management measures were implemented. The project environment and background conditions are summarized, and design issues and constraints are identified, along with the project development process. Specific case examples are discussed regarding consolidation of access, driveway reductions and U-turn accommodations.
