As far as the Erie canal goes it will be built but in a different place as New York is still going to want to get its hands on those grain shipments. Part of the canal will cut across the Niagara peninsula another from Lake Ontario to the Hudson.
At most I see two transcontinental railways being contructed with Canadian cities linking up to the northern one. They'll probably be built in the same place as OTL as the northern interests in New York and Chicago will not want to be muscled out by any trans-Mexico line.
We may see an earlier St. Lawrence Seaway constructed
