The east–west Santa Tecla Freeway, RN-21, is the very first freeway to be built in El Salvador. The freeway passes the northern area of the city of Santa Tecla, La Libertad. It has a small portion serving Antiguo Cuscatlán, La Libertad, and merges with the RN-5 (east–west, Boulevard de Los Próceres/Autopista del Aeropuerto) in San Salvador. The total span of the RN-21 is and is currently working as a traffic reliever in the metropolitan area.
Initially, the (Santa Tecla Freeway) RN-21 was going to be named "Boulevard Diego de Holguín" in honor of the first mayor of San Salvador, Diego de Holguín. It was finally named "Bulevar Monseñor Romero", though with much disagreement; the name is still in dispute, due to its political motives by El Salvador's former president Mauricio Funes of the FMLN party who also changed the name of El Salvador's international airport, historically known as Comalapa, to Monseñor Óscar Arnulfo Romero y Galdámez for political purposes and to gain votes for the FMLN.[1]
The first phase of the highway was completed in 2009, and the second phase was completed in November 2012.[2] The expressway also contains a bicycle lane.
The road was planned in 2006, due to increasing vehicular traffic in the west side of the San Salvador Metropolitan Area, which consists of three cities: Santa Tecla, Antiguo Cuscatlan, and San Salvador. The Panamerican Highway breaks for 2.5km (01.6miles) at the historic downtown of Santa Tecla, where the traffic flow collapses almost every day during morning and evening rush hour.[3] This road was the only exit form the metropolitan area towards the western departments. RN-21 has a function of a "periferico" it goes around the northern side of the area, then down on the west to divert traffic from the historic downtown.
The first phase of the RN-21 was completed and opened in November 2009, and Phase II was supposed to start in January 2010. Allegedly the current minister of public works stole money that was fund Phase II. He was replaced and charged. Phase II was abandoned until early December 2011, when the Ministry of Public Works recovered the money needed to restart construction and to pay for the damage to the foundations of Phase II due to the storm outbreak in the country from May – November 2011.[4]
Minister of Public Works (MOP-Ministerio de Obras Publicas), Gerson Martinez announced that RN-21 would be completed in 360 days.[5] As in Phase I, the second phase would create six lanes (three in each direction) with a width of 3.65m (11.98feet) and emergency lanes on the shoulders with a width of 2.5m (08.2feet). This work, besides boosting to development, will generate hundreds of direct and indirect jobs and will be the fastest and easiest way to go to San Salvador without going through Santa Tecla. According to traffic studies the road will support over 100,000 vehicles daily. Second phase costs were predicted to be $31,925,558 (USD).[6] [7]
