TULSA - As part of a US-169/SH-266 interchange improvement project, all lanes of US-169 north and southbound are closed through 6 a.m. Monday.
Westbound SH-266 traffic is detoured to Highway 167 to I-44/244 and then to US-169.
Eastbound SH-266 traffic is detoured to Mingo to 36th Street North and then to US-169.
During the weekend, ODOT crews will take down the eastbound SH-266 bridge. ODOT expects significant delays and advises drivers to avoid the area if possible.
Speed limits will be lowered to 25 mph in this work zone.
After the lanes reopen Monday morning, east and westbound SH-266 traffic will shift to the westbound bridge and narrow to one lane in each direction for the foreseeable future.
The left lane of north and southbound US-169 will be closed at SH-266 until mid-March; delays can be expected, especially during peak travel time, according to ODOT.
The cloverleaf ramps at the US-169/SH-266 junction will be closed. Drivers on SH-266 will still have access to US-169 via left turns onto ramps at this interchange.
The $9 million project replaces two structurally deficient bridges built in the early 1960s and with one new bridge.
ODOT spokeswoman Kenna Carmon says 60,000 cars travel this portion of US-169 each day in this area. She says 9,000 cars and trucks travel this portion of SH-266 daily.
Ramps will be reconfigured from a cloverleaf style to a diamond style interchange.
The entire project is scheduled for completion early 2015.
