On 23 March 2020, the Heredia terminus section was bifurcated to improve the traffic, by making Route 5 into an Heredia outbound section, and annexing 1.5 km of the immediate north road, Avenida Joaquín Rodríguez, as Heredia inbound section, with a new semaphore at the joining point with Route 3. This bifurcation provides two lanes in each way, but the right lane will be for public transportation exclusive use at peak traffic hours (06:00-08:30 and 15:00-19:00). Both sections converge at the Route 5 and Calle 35 point, to one lane in each direction.[1] [2]
