ROME (AP) — An Italian court has authorized the city of Venice to dismantle egg-shaped cars and tracks that were designed to make a Grand Canal bridge accessible to people with disabilities and hardly been used.

The mobility system was added to the Ponte della Constituzione (Constitution Bridge) at a cost of about 2 million euros (about $2.3 million) and hasn't worked well since it started running in 2013.

Visitors complained it was slow and the cars were unbearably hot during the summer.

A glitch trapped two Americans inside a car in May 2015.

The Court of Audit cited ongoing infrastructure costs in its decision sanctioning the system's removal. It notified Venice Mayor Luigi Brugnaro on Saturday.

Designed by Spanish architect Santiago Calatrava, the bridge links Piazzale Roma to the Santa Lucia rail station.
