Due to the reconstruction of I-35E, the Gateway Trail is CLOSED from Cayuga Park to L'Orient Street . Here is a detour from MN-DOT.
The detour map brought to my attention that there is a new segment of the Trout Brook Trail! I have now biked and reviewed it. Heading through a new nature sanctuary* on a converted railroad grade, it comes tantalizingly close to the Gateway without actually connecting to it (but that's the section of the Gateway that's closed, anyway). Saint Paul's page on the Trout Brook Trail says that it will be connected to the Gateway at Cayuga Street in 2016.
*The trail is open, but the surrounding Trout Brook Nature Sanctuary is still under construction.
