The installation of BEJS on this bridge was done in two phases to minimize traffic disruption.

Phase I was done in the breakdown and slow lanes in the morning. At the lower left of this photo the sandblasted (white) angles and newly installed BEJS from the morning’s installation are seen.

Installation of the fast and middle lanes began at 11:00 pm.
