Replacement of the Post Avenue Long Island Rail Road (LIRR) Bridge is set to begin in late
March or early April, with the Metropolitan Transportation Authority (MTA) Board approving a $9.7 million contract for the design and construction of the new bridge last week.
The new bridge will replace a deteriorated span that has been in service for 102 years. The new span will be safer for vehicular traffic, meeting the latest standards and requirements of the New York State Department of Transportation. The rebuilt bridge will increase the clearance to 14 feet above the roadway, a full two feet and two inches higher than the current clearance of 11 feet, 10 inches.
The increase in clearance is expected to improve train service by reducing the number of instances in which over-height trucks strike the bridge, which can result in train delays for thousands of LIRR customers. Though structurally sound, the bridge has been struck by trucks between five and nine times per year in each of the past six years.
Similar to the recently completed Ellison Avenue bridge repair project, the contract was packaged as a “design-build” contract.
“With the award of this contract, we’re working to improve Main Line train service with a modern bridge with a higher clearance that will reduce bridge strikes, and the train delays that can result,” said LIRR President Patrick A. Nowakowski. “And by using the design-build contracting method, we’re doing this in the most efficient and fastest way possible.”
The contract for the bridge reconstruction was awarded to Halmar International Inc., an engineering and construction company based in Nanuet, N.Y. There were four other major competitors answering a Request for Proposals, which was issued by the railroad in August. After careful analysis of all the proposals, the LIRR deemed Halmar’s offer the best from both a technical perspective and price. Halmar’s proposal of $9.7 million was $1.6 million below the LIRR’s cost estimate for the project.
LIRR officials said the reconstruction work would require one weekend train service outage on the Main Line, projected for October 2017. They anticipate this is also the only weekend when full road closure will be necessary. The project is expected to be complete by the end of 2017.
Under terms of the contract, the LIRR and Halmar have set a goal of having 17 percent of the subcontracting work performed by minority-owned, woman-owned and disadvantaged business enterprises, an initiative that Governor Andrew Cuomo has made a priority for state agencies as well as the operating agencies of the MTA.
In addition to improving conditions for LIRR customers, motorists and truckers, the new bridge will also be able to accommodate a third Main Line track, in line with other infrastructure improvements in the corridor over the years and also in line with Cuomo’s proposed LIRR expansion project.
