Fremont Bridge

Highlight (Segment) • Bridge

Careful when riding North-to-South. If you want to continue on the Chesiahud Lake Union Loop trail, you need to use the long three-stage crosswalk across 4th Avenue BEFORE crossing Nickerson St/Westlake Avenue. The trail branches off the sidewalk to the East side of Westlake Ave. If you cross after that intersection, you will need to cross back again to get on the trail rather than the street.
Riding South-to-North, beware of cars cutting you off by turning right at the "Waiting for the Interurban" statue. They don't seem to look out for cyclists right there.

Gas Works Park

Highlight • Monument

Gas Works Park was developed on the site of a former coal gasification plant on the shores of Lake Union, directly across from downtown Seattle. In 1965, the city purchased the 19-acre tract for parkland. The park, with its Great Earth Mound peak, was opened to the public ten years later (constructed from on-site excavated material). The location provides unsurpassed views of the lake and metropolitan skyline. The boiler house was converted into a picnic shelter with tables and fire grills, while an old exhauster-compressor structure was turned into an open-air play barn with a maze of brightly painted machinery for kids. In 2013, the Gas Works Park was added to the National Register of Historic Places.

University Bridge

Highlight • Bridge

The most efficient way to cross Lake Union on the East side of I-5. Montlake area is always under construction (2024) and can get confusing as the lanes keep switching all the time. If the bridge doesn't take too long for ships to pass underneath if it is up. Bike path is plenty wide and you feel pretty safe from the traffic. Going southbound, exiting the bridge can be a little sketchy. Often use the pedestrian walkways to get to where I am going (often need to cross over all the lanes to go east, which just isn't worth the traffic battle).
