Route 147 faces daily congestion. National Route 310: Begins in the Santa Ana district and continues through Pozos northwards, parallel to Route 147. It runs through Route 27 without any official ramps connecting them. Since Route 310 runs through Pozos, connecting to Escazu, it is still an alternate route to Route 27. It is not recommended unless the previous routes are heavily congested. Route 310 ends in Route 121 in the Escazu canton after once more passing through Route 27 (with connecting ramps) due to its southwards facing U-shape. National Route 311: Connects the district with the Salitral district to the south. The route ends in the town of Salitral. Public transportation Bus routes in Santa Ana are yet to be officially named and numbered. Buses serving the Santa Ana-Escazu-San Jose routes are currently identified by their blue color scheme. The route is currently managed by CILT. Buses serving the Santa Ana-Belen route follow a predominantly white with violet stripes scheme. The route each bus takes is indicated on the windshield without following any defined standards; passengers may ask the bus driver for clarification if needed. Fees for each route are set by the national authority- they cannot be modified and must be indicated and paid upon entry. There are discount plans available for 'Golden Citizens' (elderly residents) upon request at the local government offices exclusive to the Santa Ana-Escazu-San Jose bus services. Santa Ana's authorized taxi service is officially located on Main St (Calle Central), in front of the church as well as further north (between Central & 5th Ave). Official taxi services follow the national standards: Red-colored with yellow triangles on the side indicating their permit number; licence plates begin with TSJ (Taxi San Jose). Taxi services with official plates from other provinces (TH, TP, etc.) are not permitted to begin their service in San Jose and vice versa. They can, nonetheless, begin their service within their permitted province and finish it elsewhere. Since Santa Ana is located in the Province of San Jose, said limitations apply to non-TSJ plate wielders except Airport Shuttles and Taxis which operate freely in all provinces but are only available if called or at the airport.
