The purpose of the study was to evaluate the capacity on Sullivan Road and assess the impacts of regional projects and localized growth to the transportation system. The City of Spokane Valley was successful in receiving STP funding for the study in 2012 and contracted with HDR in 2013 to prepare the study. The consultant team and the City have been involved with the study over the last year. The study evaluated existing conditions, projected and evaluated future conditions, and identified both motorized and non-motorized improvements for consideration that will enhance the transportation system along the Sullivan Road Corridor. A series of business stakeholder public outreach events has occurred, most recently in October of The study reflects and incorporates input from the stakeholders. The purpose of this presentation is to provide an overview of the process and findings documented within the report. The intent is to finalize the report this year.

2 Sullivan Road Corridor Study Administrative Report 12/16/14

3 Background 2 Planned Regional Roadway Projects Impacting Sullivan Road Corridor Bigelow Gulch North South Corridor (NSC) Bigelow Gulch Spokane County Project Generally widen corridor from Francis to Evergreen 2-lanes each direction with a turn lane Construct direct connection from Forker to Sullivan Construction estimated to occur near 2022 North South Corridor Washington State Department of Transportation Currently completed to Francis (Bigelow Gulch connection) Planned to connect with I-90 Construction timing is funding dependent

4 3 Background Sullivan Road between I-90 and SR 290 one of busiest freight routes Sullivan Road connects to Spokane Industrial Park Large impact on corridor expected by completion of Bigelow Gulch Spokane County identified need for Sullivan Road corridor to be 3-lanes each direction City wanted to re-evaluate needs of the corridor and validate impacts from Bigelow Gulch and NSC City applied for STP funding in 2012 Successfully awarded study funding in 2012 $173,000 STP funding / $27,000 City match ($200,000 total) City contracted with HDR in June of 2013

5 4 Purpose and Goals Develop a Corridor Plan (20+ year vision) that addresses transportation, community, and system preservation needs. Determine whether the Sullivan Corridor should be widened (7 vs. 5 lanes) Determine whether other intersection capacity improvements are needed Quantify impacts of regional projects (and timing) on Sullivan Corridor traffic Validate/Confirm current planned projects (Bridging the Valley and concrete paving projects) Evaluate and provide recommendations on multimodal (transit and nonmotorized) transportation, access management and traffic safety future projects

28 27 Key Questions and Answers 1. How will the Sullivan Road Corridor be impacted by the regional NSC and Bigelow Gulch projects? Timing/Completion of the remaining NSC project does not have a significant or measurable impact on traffic volumes that are anticipated to use the Sullivan Corridor. However, completion of the final phase of the Bigelow Gulch Road project between Forker Road and the proposed new connection to Sullivan Road will have a more measurable impact to traffic volumes on Sullivan Road between SR 290/Trent and the Wellesley intersection.

29 28 Key Questions and Answers 2. Does Sullivan Road Corridor need to be widened to a 7-lane arterial? No, keep as a 5-lane arterial with spot intersection improvements based on the latest travel demand forecasts.

30 29 Key Questions and Answers 3. Should the Bridging the Valley (BTV) improvements on the Sullivan Road overpass at SR 290 be built before the Bigelow Gulch Road /Forker Road project completed? Yes, BTV improvements at Sullivan (and associated interchange capacity improvements of the SR 290/Sullivan Road Interchange) should be programmed/prioritized ahead of the completion of Bigelow Gulch Road/Forker Road Project.

31 30 Key Questions and Answers 4. Confirm/validate that the BTV improvement plans (developed in 1997) for the Sullivan/SR 290 interchange are appropriately scoped to accommodate 2040 demand based on updated regional traffic model. The right turn pocket/lane for north-to-eastbound traffic is not necessary based on the latest 2040 traffic forecast and operations analysis. However, consideration should be given to including width for a multiuse (pedestrian and bike) shared-use path in this area.
