Paved path that hugs the side of 520 from Redmond to near the 405 interchange in Bellevue. A new section begins at 108th Ave NE and heads west to Evergreen Pt Road - parts of it are open now (see pictures) and parts are set to open around the end of October 2014. There is a fence between car traffic and the trail, and sometimes a wide buffer. Rather hilly -- the steepest section is the start in Redmond, where the trail goes from 70 feet to 400 feet elevation in the first 4/10 of a mile. There are no stops on the western half from NE 24th St to 148th, but road crossings exist at 148th Ave, 40th St, 51st St. and West Lake Samm. Pkwy. Trail surface is good, though occasional road debris migrates into the trail and vines grab lazily at the edges. Watch out for rabbits and maybe a shy coyote in the section between 51st and 148th, especially at night. The newest section of trail is partially open as of 10-19-14 but some of the underpasses still need paving. An anonymous source told me they should be done with this section by about the end of October.
Eastern end of the trail branches off from the Sammamish River Trail just west of the ped bridge.

1. The state is extending the 520 trail westward to the 520 bridge and UW (see map on page 4)
2. Redmond's long-term plans recommend grade-separated crossings for the 520 trail at 40th St (item #8), 51st St (item #10) and West Lake Sammamish Parkway (see item #176).
3. Plans have been proposed to replace current road crossings with tunnels or bridges.
Directions: East trailhead connects with the Sammamish River Trail next to Leary Way. West trailhead is on NE 24th St, 1 block west of 124th Ave NE. Follow NE 24th St westward, go RIGHT on Northup Way (no shoulder, narrow lanes until about 108th Ave). The newest section of trail begins on the south side of Northup Way at 108th Ave and heads west, passing under Bellevue Way and NE 92nd Ave and hugging the north side of 520. Sometime in 2016 the trail across the new 520 bridge is supposed to open to allow rides to the U-District in Seattle!
Cross West Lake Sammamish Parkway and continue a couple blocks along Leary Way to trail junction.

When the freeway was widened, they were kind enough to build a bike bridge too!
Near the west end of the trail, the freeway is just on the other side of a concrete divider.
