The [[RN-21 (Boulevard Diego Holguin)|RN-21 (Bulevar Monseñor Romero)]] (East–West) was the first freeway to be built in [[El Salvador]] and in [[Central America]]. The freeway passes through the northern area of the city of [[Santa Tecla, El Salvador|Santa Tecla]], [[La Libertad Department (El Salvador)|La Libertad]]. It has a small portion serving [[Antiguo Cuscatlan]], La Libertad, and merges with the [[RN-5 (Autopista Comalapa)]] (East–West, Boulevard de Los Proceres/Autopista del Aeropuerto) in [[San Salvador]]. 

The total length of the RN-21 is {{convert|9.95|km|mi}} and is currently working as a traffic relief in the metropolitan area. The RN-21 was named in honor of [[Óscar Romero]]. The first phase of the highway was completed in 2009, and the second phase in November 2012.
