The eastern side of the new bridge replacing the old Schuyler Heim Lift Bridge is open and both north and southbound traffic is being routed on it while the old lift bridge is demolished and the western side of the new bridge is bult.
New signage installed for northbound traffic on the Terminal Island Freeway crossing the new bridge indicates that SR 47 exits off itself as “Exit 5” at Henry Ford Avenue. Exit 5 is an exit number for SR 47, as SR 103, which begins as a short concurrency with SR 47 at the Seaside Freeway interchange, begins only 1½ miles south of this point.
I’m not entirely clear about Caltrans supremacy rules when it comes to which of two concurrent non-interstate routes gets preference over signing their exit. I’d always assumed the lower route number won out. Having SR-47 be the signed exit rather than having the continuation of SR 103/Terminal Island Freeway be a left exit off SR 47 indicates that they are treating SR 103 as the mainline. But obviously if they were taking the position that SR 103 exit numbers should have supremacy, then Henry Ford Ave. would be Exit 2 instead of Exit 5.
The wildly out-of-date CalNEXUS page
doesn’t have anything about future exit signing for SR 103 and only has a signing chart for the south end of SR 47 on the western side of the Vincent Thomas Bridge.
