Heads up...construction on toll road between Aguascalientes and Zacatecas yesterday, Sunday, delayed us by one hour...we reached Mcallen and got on the bridge for Anzalduas crossing and it took us 4:45 -- that is 4 HOURS and 45 minutes to cross into US. Asked the border guard about the other bridges and he said Hidalgo just as bad and Pharr is CLOSED. Do not try to cross on Sundays he said that is the worse time!
