Whether the Vicksburg Bridge Commission runs a deficit or a surplus in fiscal 2013 depends on the progress of work to shore up piers and the soil on the Mississippi side of the U.S. 80 bridge.

Expenses outpace income by nearly $1 million on a draft adopted by the five-member panel Wednesday. Spending projected at just more than $2.2 million includes $715,000 for the project, planned for about a decade.

In June, Georgia-based Hayward Baker was awarded a $549,440 contract to perform the work, much of which will be around pier 2, the first large pier on the Mississippi side. The support structure has moved 24 inches to 30 inches west since the bridge was built in 1930, according to annual inspection reports.

Income is estimated at $1,241,500 and assumes $1.1 million from tolls on rail cars that cross the river in either direction. An annual audit on bridge finances is expected to be completed by next month.

Finances ended the commission’s fiscal year July 1 at $841,500.24 under budget, mainly due to delays in the slope project, superintendent Herman Smith said.
