Is the CA-9 North highway to the Atlantic ports being widened?

Yes. The CIV launched an international public tender to widen to four lanes 31 km of the CA-9 North between km 85.3 (El Rancho, El Progreso) and km 120.3 (Teculután, Zacapa), over a 36-month term;… the first phase does not include a bypass. Prensa Libre documents an associated loan for the Teculután–Mayuelas stretch. The CA-9 North is the road corridor to Santo Tomás de Castilla and Puerto Barrios. The loan amount and the status of the award are not.
