Then, in 1986, a portion of its vast interior was opened to visitors.

On July 14, 2012, the following portions of the expansion project were opened to the public:

In 1975 a portion of the residence was opened as a satellite seniors home for a local long term care facility.

The top portion is opened and folded back flat to form an 8-men sleeping space.

The bonds were paid off before a second portion was opened in 1976.

The first portion of Stage 3 was opened to the public on December 7, 2007.

A portion of this operation was later opened to the public, so visitors could enjoy an indoor green space.

The first portions were opened in 1969 and it has expanded to 11 lines with 175 stations.

This new portion was opened to traffic on March 29, 2011.

Construction on the facility began in 2001 and portions of the road were opened to traffic in May 2004.
