Trucks keep hitting the Tudor Road overpass. The rebuild is years out

Trucks keep hitting the Tudor Road overpass, and the fix is years away. The bridge, built as a compressed diamond in 1976, stands at 16 feet of vertical clearance, below the current minimum, and repeated truck strikes have forced extensive repairs. The replacement will raise clearance to at least 18 feet at a crossing that carries about 50,000 vehicles a day north and south and about 36,500 east and west, one of Anchorage's and Alaska's busiest.

The Federal Highway Administration has now added $912,130 to that rebuild, the first new money since the award was signed May 22, 2023 with $2.8 million. The Aug. 4 obligation brings federal commitments to $3.7 million against $5 million in total award funding, of which about $928,000 has actually been spent.

DOT&PF, the state transportation department, says on the project's FAQ that the job is 93.4 percent federal through the National Highway Performance Program with a 6.6 percent state match. The award record does not show that split. It lists $1,322,320 as non-federal, exactly the $5 million total minus the federal money obligated so far, and that $5 million is the award, not the price of the interchange. Neither the project page nor the FAQ states a total cost, and no record reached states why the two figures do not match.

A May 19 memo from consultant DOWL narrowed the design options to a tight diamond interchange. "The project team recommends advancing Alternative 2" for further evaluation in the environmental document, wrote Steve Noble, DOWL's project manager, and project engineer Sam Tyler, who added that the recommendation "is not a final preferred alternative under NEPA." The diverging diamond and displaced left-turn layouts would have taken substantial private property, the memo found, and the diverging diamond and single point forms do not readily handle the ramp-to-ramp movements oversized loads use. The concept is not new. The Anchorage Planning and Zoning Commission unanimously approved a concept report containing that design in April 2026.

Two gates fall this month. AMATS, the metropolitan planning body for Anchorage, records environmental document approval and the 35 percent design review both due in August 2026. DOT&PF's notice also disclosed that the project would encroach on the 100-year floodplain of Fish Creek, most likely during culvert installation, with no net change to base flood elevation expected.

The memo lists ten briefings and records no opposition to the tight diamond. It is the only account of public reaction in the records reached.

Start dates differ across sources. AMATS lists 2029, the state notice says summer 2030, the project schedule page says 2029 to 2031, and every record ties construction to available funding.
