The Federal Highway Trust Fund is running low on money.
Because of that, Congress is taking 30 days to decide what to do next and put a hold on distributing the funding.
As a result, the Oklahoma Department of Transportation put $46 million in projects schedule to go for bid in November on hold.
One of those projects includes expanding the L.L. Tisdale west to the river.
Another project ODOT temporarily put the breaks on involves real-time traffic information message boards on I-44.
The boards would be used on the highway between Riverside and Yale during the widening project.
"Now we're dealing with a lot of unknowns. Until we get a certainty in our federal monies, that uncertainty really creates pause for us," said the Director of the Oklahoma Department of Transportation, Gary Ridley.
But despite those road bumps, the Transportation Commission gave the green light for several projects in Tulsa Monday, including one to expand I-44 between Yale and 41st Street.
"We'll be replacing the bridges that go over Darlington on I-44 and expanding that main line paving from four lanes to six lanes," said ODOT Division 8 engineer, Randle White.
The commission also awarded a bid for building an overpass on Highway 75 at 111th and another bid to replace the bridges at I-44 and 163rd East Ave.
"We're always glad when we can go out and replace some of our older structures and our older sections of pavements," said White.
As for the projects that are on hold, they could stay that way until the first of the year.
