The first plate was installed Tuesday.

1.2 MILLION pounds of pressure applied to the post tension rods to be able to install the new plates. This process is estimated to take 10-15 days.

As 24/7 operations continue, the contractor is making significant progress on the repairs, TDOT said Monday.

Post-tensioning (PT) stressing started over the weekend, and Monday morning crews were able to remove the inner phase one plating. They are now removing the fractured member of the tie beam.

What’s Next:

  • Once the fractured section is removed, the phase one outboard plate will be removed.
  • Once this work is completed, the PT stressing operation will resume.
  • Once the PT stressing operations are completed, installation of the permanent inboard structural plating will begin.
  • The permanent repair plates have started to arrive. Deliveries of this steel will be ongoing through early next week.

In-depth inspections of the bridge continue. If any issues are found during the repairs, it could affect the bridge’s opening date. The safety of the workers and the public is our number one priority, TDOT said.

From TDOT’s June 18 update:

The post-tensioning (PT) process could begin as soon as Sunday, but a lot of prep work must be done first.

  • Weldment/PT anchor installation is ongoing. Final drilling/bolting/welding will continue through today and tomorrow.
  • Installation of PT bars has started. Work on this will continue through today and tonight and should be completed by Saturday.
  • Offloading and installing PT equipment, jacks, etc., will start today and continue through the weekend.
  • 24/7 operations started Wednesday night.
  • Permanent plate fabrication has begun, and delivery of the first plates can be expected next week.

In-depth inspections of the bridge continue. If any issues are found during the repairs, it could affect the bridge’s opening date. The safety of the workers and the public is our number one priority, TDOT said.

June 14 update:

  • Threaded post-tensioning (PT) bars have arrived! These are high-strength bars that have been specialty fabricated for the project. Installation of these bars will begin this week.
  • Both PT weldments/anchors were delivered this weekend and are being installed. The first anchor is 50% complete. Installation of the second anchor will start as soon as tomorrow.
  • Steel strengthening plates and splice plates for the permanent repair are being fabricated.

As TDOT contractors continue their work, crews continue to monitor the I-55 Bridge.

A second lane was added over the weekend to the I-55 southbound ramp to help traffic flow more smoothly.

TDOT added that the I-40 Bridge is still being inspected. So far, TDOT crews have found “nothing of concern”.

If something is found during the inspection, it could delay the bridge’s reopening.
