Please review my map writing

Topic:

The two maps below show road access to a city hospital in 2007 and in 2010. Summarize the information by selecting and reporting the main features and make comparisons where relevant.

My essay:

The two map compare changes in the layout of city hospital underwent a 4- year period from 2007.

In general, the most notable changes are the construction of a new bus station to the southwest and two roundabouts of the central southern area.

In 2007, to the north, the city hospital was enveloped by ring road, which remained unchanged after four years. By 2010, the bus stops along the Hospital Road were removed completely, restoring the west-side area into a novel bus station, which was accessed via two new roundabouts. The first roundabout is at the intersection of City Road and Hospital Road, while the second is at the other end of Hospital Road, at the junction with the hospital ring road.

The eastern side of Hospital Road experienced substantial transformation of the car park. In 2007, staff and customers used the same parking lot led to the ring road. However, this area was assigned exclusively for hospital employees while a new public car park were built adjacently to the right of hospital.

Thank you for your seeing. Can you give me a score, please?
