Description: B-3349 - HYDE COUNTY Location:Bridge #32 on US 264 over Rose Bay Creek
Item(s) of Interest:
Project paired with Site 7 near Englehard.
Let in April 2006.
Permanent sheeting at end bents.
Precast bent caps with prestressed piles.
Top-down, staged construction.
Temporary traffic signals for one lane, two way traffic.
Observations and Points of Discussion:
Unusual L-shape rail was used to increase the rail to rail horizontal lane width.
The L-shape rail will not be used routinely.
There was some discussion on the scour predictions that necessitated costly 40' long sheet piling at one end bent.
There was concern that the excess grease used in the bent cap form pockets may prevent proper bond between the piles and the caps.
There was some discussion on the benefits of precast elements at this site. It was noted that the cast-in-place alternative would have required de-watering the site.
Despite the numerous logistical challenges presented by this site, the project accomplished the goals of shortening the construction time and avoiding moratoriums.
