 What I've got is a tiny through-route map of the city that appears in the back pages of a road atlas covering the whole country; it just labels it ""Dr. Norman Bourlong"". On line, there's one here (not very good) and a pictorial one here. Both seem to indicate the name changes to ""5 de febrero"" when it hits the south rim city centre. The second one labels it ""C. Norman E. Borlaug"", which indicates that it's a ""calle"" (street), not an ""avenida"". (The first map spells it Borlaung, too  must be very common for it be spelled wrong by the locals.)  "
