 Two other spurs of I @-@ 87 were planned but never constructed . In the Hudson Valley , I @-@ 487 would have run along the Hudson River from I @-@ 87 and I @-@ 287 in Tarrytown to I @-@ 84 east of Beacon . The other spur , I @-@ 687 , would have connected I @-@ 90 in Albany to I @-@ 87 near Albany International Airport in Colonie . Both routes were cancelled in the 1970s as a result of public opposition .
