Alternate rail links to Jacksonvile's ports other than the exising Gross line to be studied

North Florida Transportation Planning Organization will perform a study in 2013 to determine if running a railroad through Northern Duval County to connect CSX's main line to the new Jax ports on the St. Johns River is a better alternative that the abandoned Gross Line. The Gross line was built in the mid-1920s from Gross (at the I 95-US 17 interchange just south of the GA-FL line) to Callahan. This allowed Seaboard Air Line to divert their passenger trains heading for Central and South Florida on their main line that paralleled US 17 in Georgia to bypass the congested Jacksonville Terminal. The 14-mile segment has been abandoned since 1985. As it is now, once the port is opened, trains will have to use their track that runs south along US 17 into the urban core of Jacksonville than curves west to join the main line in Grand Crossing just south of Edgewood Ave.  The speed limit along this track is very low because it crossings many grade crossings and an old swing span bridge across Trout River.  (Thankfully, FDOT has just built an overpass over this 15-mile sub and eliminated the US 1/23 grade crossing south of Edgewood Avenue.)  These other options will have to cross US 1/23 and SR 115 (Lem Turner Road), the two main highways that connect Jacksonville to Callahan, at grade. Plus, a costly overpass will have to be added on I 95 to allow this track to pass underneath. I, for one, hope they decide to use the Gross line as  the port link because the bed is already there.  Link to the story as reported in the Florida Times-union is provided below.
