Work has begun on the reconfiguration of the I-44/US-75 interchange in Tulsa, Oklahoma. The $252m project attracted attention after its first phase left a series of bridge piers locals named “Tulsa’s Stonehenge”.
Work was temporarily halted after the completion of the $90m first phase in 2023. It has now become available again, after the Oklahoma Department of Transportation received two federal grants worth a total of $95m.
Work includes rolling three phases into one, with the scope including:
- Widening US-75 between 71st St. and 41st Street
- Replacing the US-75 interchange at 61st Street
- Adding a new frontage road between 61st St. and Skelly Drive
- Extending and connecting 51st Street. under US-75
- Building a pedestrian bridge over the railroad along 51st Street near Elwood Ave.
The project is due to be completed in summer 2028, dependent on weather conditions.
