What is this section of road doing in a building site?

14 rue Alasseur is served by metro line 6, 8 et 10 at La Motte-Picquet - Grenelle station

This section of road is the entry to a car park. It has 250 places. To enter the car park, you need a remote control and you have to stop with your car at the yellow line. I've heard from a resident that a fire took place inside the car park and three cars were burned in 2011.
