Background

The Southport to Harbor Roadway Project originated as an effort to address deteriorating pavement conditions along Southport Parkway. The project has since evolved into a Complete Streets initiative designed to rehabilitate pavement and improve multimodal safety through the addition of sidewalk infill, new bike lanes, upgraded utilities, and enhanced pedestrian and transit access. The project corridor includes:

• Harbor Boulevard – from the US 50 on/off ramps to Industrial Boulevard

• Industrial Boulevard – from Harbor Boulevard to the Palamidessi Bridge

• Lake Washington Boulevard – from the Palamidessi Bridge to Southport Parkway

• Southport Parkway – from Lake Washington Boulevard to Promenade Street

The corridor experiences a high percentage of truck traffic, which has accelerated pavement deterioration. While the City’s recent Neighborhood Pavement Preservation Program provided temporary repairs along Southport Parkway between Lake Washington Boulevard and Ramco Street, a long-term reconstruction solution is now required.

In 2022, the City completed preliminary design (35%) and several technical studies under a prior consultant contract. These documents will be made available in the Attachments section of this RFP:

• 35% Schematic Design

• 35% Construction Estimate

• Storm Drainage, Sewer, and Water System Evaluation and Analysis

• Geotechnical Pavement Evaluation

• Life-Cycle Cost Analysis (LCCA) Memorandum

• Phase 1 Environmental Site Assessment (ESA)

• Traffic Analysis Report

• UPRR Exhibit

The total project construction cost is currently estimated at $37 million and will likely be delivered in multiple construction phases. The project is federally funded with Regional Surface Transportation Program (RSTP) funds and recently received Enhanced Infrastructure Financing District (EIFD) funding from the City to advance design through 100% Plans, Specifications, and Estimate (PS&E).
