ORLANDO, Fla. — A busy roadway in downtown Orlando was temporarily shut down Monday for overnight "I-4 Ultimate" bridge repairs.

Florida transportation officials closed Colonial Drive at Interstate 4 to install a temporary fix to cracks found in the bridge.

Steve Olson, a Florida Department of Transportation spokesman, said the agency has been watching the pier bridge for weeks to determine whether it would be ready to open for traffic.

But during that process, they found cracks in the infrastructure, he said. The bridge is structurally sound, but FDOT determined it wants to install a temporary fix to relieve some of the weight from the bridge, Olson said.

Crews will work overnight Monday into Tuesday and hope to open Colonial Drive by Tuesday morning before rush-hour traffic hits; however, weather could delay their progress, Olson said.

Meanwhile, drivers should plan a little extra commute time to take the detours.

As drivers approach the intersection, they will notice police officers stationed at different points to help drivers.

The bottom line is, drivers cannot get through the intersection or get onto I-4 east from there.

If drivers usually get onto I-4 from Garland Avenue, which is just north of Colonial Drive, they will not be able to get onto the I-4 east ramp.

Drivers can avoid this roadblock by taking Amelia Street or Ivanhoe Boulevard to access I-4 east.

Eastbound traffic on Colonial Drive will be detoured to Livingston Street. If drivers are traveling westbound on Colonial Drive, they will eventually have to take Robinson Street westbound.

From Garland Avenue, drivers will be able to turn onto Colonial Drive, but only into the westbound lanes.

The westbound ramps to I-4 will remain open.

In the next few weeks, FDOT will work to design a more permanent fix to install. That installation will shut down Colonial Drive at this interchange again, Olson said.
