east/west pedestrian bridge was completed on February 15, 2011. On September 14, 2011, part of the wooden panels and support beams from the construction project collapsed on vehicles crossing the border, injuring nine people, two seriously. All northbound traffic was diverted to the Otay Mesa Port of Entry for the rest of the day, causing massive traffic jams. 2013 On the Tijuana side construction of links to connect the new El Chaparral Facility with Via Rápida and Avenida Internacional, which leads drivers to the western Tijuana borough of Playas de Tijuana and nearby Rosarito Beach, was built in 2013 (see below). 2015 Prior to September 2012, pedestrians walked from the U.S. to Mexico by crossing a pedestrian bridge, entering Mexico to the west of Interstate 5, and walking through a corridor leading to the west side of the crossing (Avenida de la Amistad). Then a temporary pedestrian crossing facility was built on the Mexican side on the east side of the crossing. This was replaced when in August 2015 Mexico inaugurated a new pedestrian crossing facility to the east of the northbound traffic lanes. For the first time foreigners are required to show passports when entering Mexico at the border, whereas previously they only had to be shown when entering the interior of the country.<ref>[http://www.sandiegouniontribune.com/news/2015/aug/19/mexico-opens-new-pedestrian-port-san-ysidro/ "New pedestrian crossing unveiled in Tijuana", Sandra Dibble, San Diego Union-Tribune", Aug. 19, 2015]</ref> 2016 On July 15, 2016, the PedWest pedestrian crossing and Virginia Avenue transit center were opened. On the Mexican side a temporary, partially enclosed walkway was opened connecting this crossing southeastward to the pedestrian bridge from Plaza Viva Tijuana that heads southwest to Downtown Tijuana. This walkway was nicknamed "Puente Chicanadas''" ("cheap/quick fix bridge") and characterized by some as dangerous, suffocating and embarrassing to Mexico. In September 2016, a definitive walkway from Plaza Viva Tijuana costing 25 million pesos (about 1.3 million dollars at the time), was opened. 2017–2019 Phase III began in September 2017, after the realignment of Southbound Interstate 5 had been completed. The project for Phase III was completed in December 2019 which resulted in an increase from 5 inspection lanes to 10. This project also includes an increase in the Northbound inspection lanes by adding 8 new lanes on the east side of the border crossing. This project does not affect existing pedestrian lanes. Architects Miller Hull Partnership were leading the third phase of the project with
