Route and access
Lane availability per direction is very irregular, with plans to widen to up to four lanes between San José and Alajuela, two lanes between Alajuela and San Ramón, then one lane until Barranca (there are no plans to widen to two lanes), where two lanes until Liberia are in construction. The road will retain one lane until the Peñas Blancas frontier with Nicaragua.
It provides access to the main airport of the country, the Juan Santamaría International Airport.
Toll booths
There are toll booths in Río Segundo, Alajuela and El Rosario, Naranjo.
History
Alfredo González Bridge defects and widening
The Alfredo González Bridge is an originally two lane per direction bridge over Virilla river, which became infamous for a detrimental infrastructure gaffe. In 2008 a metal plate expansion joint cover, (known as a platina in Spanish) between two segments of the bridge detached on the San José to Alajuela direction lane of the bridge. As it took nine years to repair the issue, the bridge, which was unnamed before, was known with dismay as the puente de la platina, translated as "the metal plate bridge".
The first immediate repair attempt involved just using solder, which quickly detached again. In 2010 the Soares da Costa company was contracted to repair the issue, which also failed as the pour-over concrete applied, was pulverized by the vehicles. The Engineers and Architects Professional Association (CFIA) and the National Laboratory of Materials and Structural Models (LANAMME) advised against this solution since its proposal.
It wasn't until 2016 that a proper solution was put in motion, by awarding a contract to the CODOCSA company to widen the bridge from two lanes to three in each direction, which by definition involved the reconstruction of the affected joint cover.
The now named bridge was reopened on May 2017, however being a three lane bridge it was deemed as already obsolete, as there is a plan to widen Route 1 to four lanes by direction between Uruca, San José and the Juan Santamaría Airport, therefore this bridge will become a bottleneck.[1]
La Guaria creek culvert sinking
On June 26, 2012, a culvert on the La Guaria creek, near Heredia, was destroyed due to heavy rains, also it was found out that instead of proper filling on the foundations of the road when constructed in the 1960s, there were tree trunks and other organic materials that over time compacted.
By 2008, a concerned neighbor presented to the authorities a proper study where it was highlighted that the situation was a certain outcome due to the urbanization of the neighboring rural areas. No actions were taken by the government authorities.[2][3]
A new rectangular culvert was built by the contracted company MECO, during construction a couple of Bailey bridges with a capacity of 40 tons were put in place, which also were destroyed by an 84-ton truck crane on November 6, 2012.[4]
San José to San Ramón enhancements
A heavy transited component of Route 1 is the segment between San José and San Ramón, from the junction with Route 39 until Juan Santamaría International Airport, the road will be widen to four lanes per direction, then from the airport to San Ramón (canton) which as of 2019 is a one lane per direction design, with several short upward segments with two lanes, will be widen to two lanes per direction.
A private foreign contractor, OAS, was awarded the project, which under the private concession model would enhance and operate the road, as in Route 27, however due to the projected expensive toll fares, the affected residential and industrial neighbors of the route, formed the Foro de Occidente (West Forum), to oppose the construction, which ultimately halted the project in April 2013,[5] and the government had to revoke the contract with a cost of US$35 million and no work done.
Fideicomiso Ruta Uno (Route One Escrow), FRU, was created by Banco de Costa Rica to manage the finances of the works on Route 1. On July 2019, FRU was awarded the control of the toll stations of Río Segundo and Naranjo, which provide the main income of the project. It is estimated that the toll will increase in price at Río Segundo from CRC ₡75 to CRC ₡200, and at Naranjo from CRC ₡150 to CRC ₡400.[5] The toll booths will include automated electronic toll collection.[6]
OBIS projects
The Obras Impostergables, or OBIS, which translates to "works that can't be delayed", were announced by the central government in June 2018, and are seventeen auxiliary projects that were created around this road segment of Route 1, that can begin construction while the remaining analysis, design and expropriation phases advance on the main road project. These include new roads to link Route 1 with other areas, new junctions as well as new lanes on bridges that are a bottleneck to the road.[5]
Work was divided in four main batches, numbered one through four, then further divided into 1, 2a, 2b, 3 and 4. On September 2019, Fideicomiso Ruta Uno received bids for batch 1, [7] their designs were ready by late April 2020, with a projected start date on mid May 2020. [8]
Archaeological findings
On August 2020 while doing excavation works for the Castella Conservatory interchange, a stone paved road from the pre-Hispanic era was found, works were rearranged to prioritize surrounding areas that would not impact the archaeological studies by the National Museum.[9]

Barranca to Liberia enhancements
This project was split into three subprojects, to widen the road from one lane per direction to two lanes per direction, four lanes in total. Initially the plan from 2008 was to widen the segment from Peñas Blancas to Barranca, but by 2015 the segment from Liberia to Peñas Blancas was deemed unnecessary.[13][14]
Cañas to Liberia widening
Meetings started in 2012 and works concluded in January 2016, for this 50 km segment of Route 1, it also adds adding a 12 km bicycle lane and proper sidewalks. Eleven pedestrian bridges, nine underground and seven tree canopy wildlife crossings were also constructed.
Three two level junctions were constructed in Cañas, Bagaces and Liberia.[15] There is a possibility to add toll booths to the segment.[16]
Limonal to Cañas
Continuing from Limonal north to Cañas, this 21 km segment started construction in September 2018, however expropriation processes delayed much of the work, which was planned to finish in 2020, pushing the delivery date to 2021. Will include seven bridges, eight pedestrian bridges and eighteen wildlife crossings.[17]
Barranca to Limonal
From Limonal south to Barranca, this 50 kilometer final segment of the widening project will connect with Route 1 and through Route 23 to Route 27. Works are planned to start in the first half of 2020. On 11 March 2020, the project was awarded to Consorcio Ruta 1 (Hernán Solís SRL e Ingeniería Estrella S.A.), and while the other segments were constructed with concrete, this section will be made with asphalt.
