Construction of a bridge crossing Guangzhou-Shenzhen Railway, which lies in Dongguan section of Shenzhen outer-ring expressway, is progressing smoothly. The total mileage of the expressway is approximately 93km, with Dongguan's section being 17.05km. It is expected that Dongguan's section will open to traffic at the end of this year as planned, making it more convenient for Dongguan citizens to travel.

The Dongguan section of the expressway is a major provincial and municipal project. Of more than 20 construction sites along the expressway, the construction of the bridge across Guangzhou-Shenzhen railway is regarded as the most difficult and one of the greatest challenges.
