#LESNERBRIDGE update from Project Manager: “The answer is we cannot launch the gantry across the channel to complete construction of the center span until. . .”

Update from email:

Folks:

It’s been a while since the last update on the project and some of you have asked why it seems that we have stopped construction of the bridge superstructure over the inlet channel. The answer is we cannot launch the gantry across the channel to complete construction of the center span until we complete construction of Pier #5. The construction of pier 5 was delayed over the summer due to an issue with one of the 10 drilled shafts installed for this foundation. This shaft was completed this past Saturday 11/18/2017 and work is currently under way to prepare the formwork for the footing of this pier.

Once Pier #5 is complete, we will launch the gantry across the inlet, set the pier segments on Pier #5 and then launch to Pier #6 (recently completed) and set the pier segments on Pier column #6. Span #6 will then be assembled by picking segments off a barge moored in this location. After Span #6 is completed, the gantry will be back-launched toward the channel to complete the other half of the cantilever section of Span #5 that crosses the channel. So for the next two months expect see a lot of activity in the area of Pier #5 (east side of the channel).

Over the next two weeks, the bridge contractor will:

· Set formwork and chip drilled shafts to specified elevation at Pier #5;

· Place column at Pier #7;
