Who doesn't love a field trip!? Transpo’s Engineering team went on a project site visit to the Microsoft campus in Redmond, WA. They met at the Bel-Red Light Rail Station in Bellevue, WA and rode the Sound Transit 2 Line Light Rail to the Redmond Technology Station. Project staff shared a history of the project, insight into the design challenges faced, and design innovations provided by the team. Transpo designed two roundabouts, channelization, signing, RRFB, traffic signal, street lighting, and ITS improvements for the project.

Transpo Group is thrilled to be leading the Martin Way Crossing Strategy in partnership with @tooledesigngroup for the @trpcorg! One of the initial tasks is to perform a series of "walk audits" along the 5 mile corridor segment to confirm issues and discuss potential solutions. The effort is funded by the Washington State Department of Transportation Sandy Williams Connecting Communities Program which was created to help make walking, bicycling, and rolling more comfortable and welcoming in overburdened communities along state and legacy highways.

Today we hosted our Great Transpo Bakeoff along with our Toys for Tots donation drive and brought our A-game to both. All the baked goods were delicious, but the Transpo turning movements cake definitely deserves a handshake from Paul Hollywood.

It was great to attend the groundbreaking event at Northshore School District's Maywood Hills Elementary. It's amazing to see progress both from the perspective of Transpo assisting with the project as well as this being a school many of our staff's children attend, including Senior Project Manager Kassandra Leingang, PE and her daughter who assisted with the ground breaking!

Transpo contributed to the modernization of Maywood Hills Elementary School by addressing access, circulation, and parking challenges on the 1970s-era site. Transpo redesigned the parking lot to separate buses from parent pick-up/drop-off and collaborated with the City of Bothell to design a separated bike lane along the site frontage.

Congratulations to @uw_bothell and Capstone Development on the opening of two more residential buildings that make up the Residential Village at UW Bothell. With the opening of these two buildings, the UW Bothell provides over 1,000 beds for students to live on campus. Transpo is honored to be a part of the design team that included architects from Mahlum to make ideas born from the Campus Master Plan into reality. Having supported the UW Bothell for over 15 years, the transformation of the campus has been amazing to watch and we are honored to continue supporting the UW Bothell in all aspects of transportation design and planning on the campus.

We're wrapping up a fantastic time at the APWA Washington Fall Conference! It was a great opportunity to connect with partners and clients at our booth and share insights on how we're shaping the future of transportation.

A special thanks to everyone who joined us at the co-hosted happy hour with our friends from HWA GeoSciences Inc., KBA, Inc. Construction Management, and Osborn Consulting —what a night of great conversation and collaboration! 🍻

And a big shoutout to our Managing Principal, Jon Pascal, for his insightful presentation on the importance of reevaluating speed limits to achieve community safety goals. It's inspiring to see how strategic changes can make a lasting impact on road safety and our communities.
