Bridge 390.2 Span Replacement

Black Rock Arkansas

Project Owner

BNSF Railway

Project Overview

MW was contracted by BNSF to replace the existing span 32 on Bridge 390.2 over Black River located near Black Rock, Arkansas. The project included replacing an existing 74’-3” TPG span with two new steel rolled beam spans, with a predrilled rock socketed H-pile foundations, installation of precast concrete bearing blocks, precast cap, and furnishing and placing riprap.

The major work was done under a 6-hour and 12-hour window for the installation of the new center cap and the replacement of the existing span.  MW employees work in synchrony to remove the old and set the 2 new spans within our allotted work window.  We worked with the BNSF Bridge and Track crew to facilitate the completion.
