would have required the construction of a rail trestle with steep grades to avoid conflicts with structures such as the Major Deegan Expressway. The Market Route East subalternative would have started at the southern end of Highbridge Yard using the existing single track servicing the Bronx Terminal Market and would have passed along the east edge of the overflow parking area at Yankee Stadium before running parallel to the Hudson Division, crossing Exterior Street to the shore at the East 149th Street Bridge, and then following the Shore Route alignment. This option would have required an at-grade crossing just north of East 150th Street on Exterior Street, would have required the elimination of 80 parking spots at Yankee Stadium, and would have required the relocation of four businesses. Trains would have had to run very slowly through this route. The remaining options were the Shore Route, the Offshore Route, and the Market Route West subalternative. The Shore Route would have consisted of a one-track concrete trestle running from Highbridge Yard to Lincoln Avenue for . To provide a clearance of , several highway bridges would have needed to be modified and the shoreline would need to be stabilized. In addition, three bridge crossings over the Harlem River would have needed to be modified. This option would have cost $58.5 million. This option would have eliminated 20 parking spaces at Yankee Stadium, would have restricted the use of a portion of the Bronx shoreline, and would have disrupted some nearby businesses. Construction on this option was expected to take 2 to 2.5 years. The Offshore Route would be very similar to the Shore Route, with the exception that it would have been constructed beyond the bulkhead and pier line from Highbridge Yard to the East 138th Street Bridge, a distance of . This option was estimated to cost $45.5 million, and would have required Congressional deauthorization of a portion of the Harlem River channel, which could have taken at least 18 months to complete. This option was expected to be cheaper than the Shore Route as its engineering and construction were simpler and because the cost of required real estate acquisitions was much lower. This option had a greater chance than the Shore Route option of getting hit by boats.The Market Route West is subalternative for the section between Highbridge Yard and the East 149th Street Bridge.
