Portland International Airport Rental Car Quick-Turnaround Facility

Project
Rental Car Quick-Turnaround (QTA) facilities are an innovative—and still fairly unusual—building type, with only about dozen in the country. A successful QTA facility efficiently and safely fuels and cleans rental cars to meet the current demands of airport customers, while being able to accommodate future growth. They are logistically complicated projects that require an in-depth understanding of traffic flow, operational function, airport safety protocol, and fueling. For Portland International Airport’s new QTA facility, Mackenzie was able to efficiently address these aspects, and in a...Learn more

West Bay Road

Project
Mackenzie was retained by the City of Lake Oswego to design a roadway safety improvement and stormwater drainage system for West Bay Road and Virginia Way, design pavement sections for West Bay Road and Virginia Way, and work with the adjacent neighbors to determine issues they had regarding stormwater and street problems. Throughout the design phase, Mackenzie engineers worked closely with Lake Oswego staff to adapt and modify City standards and still meet project goals. The re-design of this residential street utilized green street solutions, providing water quality and reduced flow on...Learn more

SW Barrows/SW Roshak Roundabout

Project
Mackenzie provided comprehensive transportation engineering design services for the Village at Scholls retail project on the north side of Barrows Road in 2008. Guided by the preparation of detailed traffic operations and safety analyses, close coordination with Beaverton staff, and intense debate at a series of public hearings, a roundabout installation was ultimately accepted as an effective mitigation tool for this intersection. The intersection consists of a major suburban collector intersecting with a residential arterial and retail site entrance. There is one circulating lane and truck...Learn more

Ronler Drive

Project
As a result of the Ronler Acres D1X project, Intel was conditioned to provide mitigation for the project’s transportation impacts by providing a City/public collector roadway connecting 229th to Cornelius Pass Road. The completed 2,100 LF, three-lane roadway includes signals both at NW 229th under City jurisdiction and at NW Cornelius Pass Road under Washington County jurisdiction. The concrete road widens out to 4 lanes at the intersections.. Cornelius Pass Road required a deceleration lane as it approached Ronler Drive. All the work within Cornelius Pass Road was permitted separately...Learn more
