The operation hours of 91 bus routes in Beijing will be extended to 10pm starting on April 14.

Xinhua News Agency reported the move is to further optimize the municipal bus network.

The operation time of the 91 routes will be prolonged by one hour on average. Some routes will be extended by up to two hours.

New routes will also run to bridge certain gaps and cover weaknesses in the current bus network. The new routes will be a supplement to the new Beijing subway line No. 5, as well as two special express bus routes expected to begin operation this year.

The adjustment will bring convenience to residents living in more than 100 residential areas.
