TULSA, Oklahoma - Expect some big delays thanks to ramp closures at a busy Highway 169 and Broken Arrow Expressway interchange.  

The Oklahoma Department of Transportation says the westbound off-ramp from the BA to southbound Highway 169 will close Tuesday evening at 7 and will be shut down until further notice.

The same goes for the southbound off-ramp from 169 onto the BA heading west.

These closures are part of a pavement project underway on Highway 169. Crews still have the 41st Street exit closed and more closures are expected over the next few months.

ODOT says the project should be finished by summer 2018.
