Structures

The LA Storm Drain system contains many notable structures, including tunnels, networks of multiple tunnels, and sites adjacent to the tunnel entrances.

Storm Drain Tunnels
Several storm drain lines are large and ideal for exploration, the following being the most notable.


 * Unit 3 Line B, a storm drain tunnel starting at the LA river and traveling under Eagle Rock Blvd.
 * Main Line 29901, a storm drain tunnel starting at the LA river and traveling under Eagle Rock towards Occidental college.
 * The Sycamore Canyon Channel, a storm drain channel starting at the LA river and traveling under Glendale

Tunnel Networks
Some tunnels connect to form networks of stormdrains, known as a complex. These must be explored more carefully due to the possibility of getting lost.

The Northeast Gallery Complex is the most notable of these, consisting of Unit 3 Line B and Main Line 29901 connecting through a small tunnel called X-Ray.

LA River Sites

 * The Bowtie Project is an 18 acre strip of land located on the east bank of the Los Angeles River in north east Los Angeles, and the gateway to the Northeast Gallery Complex
