A years-long design project will move into the construction phase in spring 2024 by addind interchange at the intersection of Highway 97 and Lower Bridge Way, allowing drivers to access the highway without having to cross two lanes of traffic, ODOT officials said at an informational session at the Terrebonne Community School on Monday. The project will also include a number of upgrades to Terrebonne's local roads, and new features called "chicanes" will be installed on both the north and south ends of town.
