Bridge Construction

SPMT Bridge Moves

LaDOTD - Well Road Bridge Replacement

This is a 4-span replacement project at I-20 outside Monroe, Louisiana. The existing bridge's lightweight concrete deck deteriorated beyond repair as a result of heavy truck traffic and its proximity to a nearby truck rest area. To reduce the impacts to nearby businesses and limit traffic impacts, an accelerated construction method was selected to replace the spans in kind using SPMTs. The SPMT move was scheduled for March 4-6, 2011.

  • 200 South over I-15,
  • Sam White Lane over I-15, and
  • I-15 Southbound over Provo Center Street.

The 200 South bridge, previously over I-15, was a two-span continuous steel girder system and was moved as a single unit on March 19, 2011. Total bridge length is 325 feet, each span is 162.5 feet. Moved bridge weight is 3.1 million pounds.

Sam White Lane over I-15, was also a two-span continuous steel girder bridge. It was moved as single unit on March 26, 2011. Total bridge length is 354 feet, each span is 177 feet. Moved bridge weight is 3.8 million pounds.

I-15 South Bound over Provo Center Street is a 2-span (141'4" -123'5") steel girder bridge. The structure is designed as simple span made continuous (to accommodate a limited staging area). Each span will be moved separately on different nights. . Moved bridge weights are 1.5 and 1.4 million pounds.

All bridges use lightweight concrete.
