water, the company utilized a specially built trestle alongside
the bridge. Thanks in large part to the company's expertise, the
project is on track to be completed in time for the bridge to be
re-opened to traffic in November 2017.

Bridging the Gap
Building a temporary work trestle alongside a bridge under
construction also figures heavily into Balfour Beatty Infrastructure's other current project in North Carolina. Earlier this year,
the company was awarded a $54 million contract to build a new
bridge over the Intracoastal Waterway in Surf City, N.C.
The new bridge replaces a swing bridge that currently spans
the waterway, which is still functional but requires a significant
amount of maintenance and needs to open for commercial
vessels passing through the waterway. To alleviate the impact on
highway traffic over the waterway, Balfour Beatty Infrastructure
is building a new bridge with a 65-foot vertical clearance, removing the necessity to open the bridge for commercial vessels.
As in the case of the Wilmington Bypass project, Boyd says
building the Surf City bridge project without disturbing the local
ecosystem and protected wetlands has been a high priority. "The
most challenging aspect of this project is definitely what we call
the in-water moratorium, which means we're not able to do any
pile driving or extracting operations from April 1 to September
30 of any given year," Boyd says.
That means Balfour Beatty Infrastructure is hard at work
building the temporary work trestle that will serve as the staging
area for the project. Boyd says the entire project will need to be
accessed from the trestle, and 176 drilled shaft casings need to be
installed before April 1. "The project is currently working double
shifts six days a week to meet the schedule," Boyd says.
Despite the aggressive schedules and extensive preparation
required for both of these projects, Boyd says they fit very well
within Balfour Beatty Infrastructure's expertise. "The access
requirements for these projects, which are related to trestles, are
what we consider our specialties on the coast," he says.
