cues created an intuitive and efficient transfer experience for 
passengers, says AECOM Program Manager Rob Kleinman. In 
addition to being significantly faster, the new route helps relieve 
stress some passengers feel about finding their gate. 
Structurally, using a straight connection between concourses 
A and B required a simpler design that was easier to construct 
than a route with more twists and turns. Koch notes that the 
pieces and parts weren’t modular, but many had consistent 
standards, which sped production and installation. “Abstract 
Group’s updated concept and collaboration with The Sheward 
Partnership removed curved elements and focused on an 
efficient building design—a nod to the new assignment. One 
direct benefit was that construction of the building framing 
progressed very quickly,” he reports. “The structural simplification 
reduced cost and schedule.”
Expanded and updated holdrooms, each with 175 power-
equipped seats, are sized to accommodate Southwest’s larger 
aircraft and increased passenger loads. A curtainwall featuring 
electrochromic glazing technology and translucent roof fills the 
space with abundant natural light and creates a more pleasant 
environment for travelers, notes Ted Blackerby, aviation principal 
with Jacobs. 
The daylit 14,000-square-foot open market concessions 
space features a new and expanded lineup of food/beverage 
and retail options. An additional 28,000 square feet of shell 
space was added down the middle of the connector, allowing 
flexibility for future operators to outfit the space as they need and 
saving BWI the upfront construction costs.  
“The ‘flex space’ provides the concessionaire a clean palette to 
come in and do whatever they need to do,” Koch says.
Shank wryly describes the approach as, “We’ll build the box, 
but we won’t fill the box with our money.” 
Two new restroom complexes demonstrate the airport’s 
commitments to sustainability, accessibility and passenger 
comfort. Having recently completed a terminal-wide restroom 
renovation that won Cintas’ 2023 America’s Best Restroom 
contest, BWI took the opportunity to improve these facilities 
even more. 
Men’s and women’s restrooms are collocated with family 
assist and nursing rooms, along with janitorial support facilities. 
Technology features include smart restroom systems with 
occupancy indicators, a maintenance feedback mechanism, 
upgraded lighting and touchless fixtures. A designated
