It's official: Voters this fall will get to weigh in on whether Seattle should invest $1.55 billion over eight years to improve transportation infrastructure, with most funding allocated to road and bridge maintenance.

The transportation levy on Seattle ballots this fall won't grow beyond $1.55 billion, despite a push by transportation advocacy groups to go bigger. A Morales-backed amendment to increase the levy's size failed Tuesday.

Councilmember Tammy Morales offered a new proposal Thursday for a $1.7 billion transportation levy that increases spending across a broad array of programs. None of her colleagues have yet backed the proposal.

A proposed amendment to the next Seattle transportation levy pushes the city to build 500 blocks of new sidewalks in five years. However, SDOT says that goal likely isn't achievable without more funding and broader changes.

The Seattle Department of Transportation's project delivery is ramping up in 2024. What does that tell us about where the department is heading under a new levy?
