Ponte Estaiada João Isidoro França, Cable-stayed road bridge in Teresina, Brazil

Ponte Estaiada João Isidoro França is a 363-metre cable-stayed bridge over the Rio Poti, divided into six spans and held by 35 stay cables. Its single concrete pylon rises to a metal observation deck almost 100 metres up, ringed by turquoise-tinted windows. The deck carries three 3.10-metre traffic lanes and a 2.15-metre pedestrian walkway, with no concrete columns standing in the river.

The structure was completed in 2010 to commemorate 150 years since the city's founding. It was named after João Isidoro França, the city's first master builder.

The bridge's name honours João Isidoro França, the first master builder of Teresina, credited in 1848 with work that helped create Vila Nova do Poti, the settlement that became the city. Its full title also marks the sesquicentennial, the city's 150th anniversary, the occasion the bridge was designed for.

The deck carries three 3.10 m traffic lanes and a 2.15 m pedestrian walkway. The lookout is reached from the east side, on Avenida Raul Lopes, by two panoramic lifts holding ten people each, with an emergency stair as backup. Visits last about 10 minutes and capacity is limited, so expect queues at busy times.

The viewing platform at the top of the mast was inaugurated on 28 February 2011, almost a year after the bridge itself opened, because elevator tests delayed it. It covers about 300 square metres, holds 100 people, and has a mezzanine modelled on the Eiffel Tower's, giving a 360° view. Access is from the east side via Avenida Raul Lopes.
