Seward Highway and Tudor Road interchange design study goes to Anchorage hearing Nov. 2

The state wants to tear out and rebuild the Seward Highway interchange at Tudor Road, one of Anchorage's heaviest bottlenecks, and the plan goes before the Planning and Zoning Commission on Nov. 2.

Along with a new bridge, the project would ease congestion through the corridor and improve sidewalks and trails for people not in cars. The review covers the highway's northbound and southbound ramps and Tudor Road from MacInnes Street to Old Seward Highway. The commission has already signed off on the state's concept for the replacement, a tight diamond design that pulls the ramps in closer to the crossing road to save space.

The money is still catching up. The Federal Highway Administration put $912,130 toward the project on Aug. 4 — its first funding addition since 2023, and enough for design work rather than construction. Environmental approval and a 35 percent design review are both still pending.

The hearing starts no earlier than 6:30 pm at Loussac Library. The engineering firm DOWL is bringing the project forward on the state's behalf.
