43rd Ave SE/Sunset Rd

June 2022 Update

Utility relocations are scheduled to begin in early July and will continue intermittently until project construction begins. During the utility relocation work there will be single-lane and shoulder closures along 43rd Ave, Maltby Rd, and at the intersections of 43rd Ave & 196th St/Jewell Rd and Sunset Road & 180th St SE.


February 2022 Update


This project has reached 90% design and the project schedule has been updated below. Utility relocation planning and right-of-way purchasing are in progress.

Description

Snohomish County Public Works proposes to construct arterial improvements to approximately 1.7 miles of 43rd Ave SE from SR 524 (Maltby Road) to Sunset Rd at 180th St SE. Construction includes the following primary elements:

  • Widen 43rd Ave SE from SR 524 north to 188th St SE to a two-lane rural section, including a separated pedestrian facility and shoulders
  • Add approximately 1,400 linear feet of new county rural road to connect 200th St SE and 196th St SE
  • Improve the existing urban section of 43rd Ave SE from 188th St SE north to 184th St SE
  • Add approximately 450 linear feet of new county urban road between 184th St SE and 42nd Dr SE
  • Install two new roundabouts on 43rd Ave SE at SR 524 and at 196th St SE
  • Install new traffic signal and turn pockets at 180th St SE and Sunset Rd
  • Add two new stormwater ponds and two underground stormwater chambers
Improvement to the rural segment of 43rd Ave SE will follow the Snohomish County Engineering Design and Development Standards for a rural roadway section, which have been developed to help maintain the rural character of the area consistent with the local and regional guidance. To address the specific needs of residents in the vicinity of 43rd Ave SE, we are proposing a pathway separated from the travel lanes. 

​Project Background

The Growth Management Act (GMA) requires Snohomish County to develop a Transportation Element (TE) as part of the Comprehensive Plan, which is used as a guide for future roadway needs. The 43rd Ave SE/Sunset Rd project has been in the Comprehensive Plan since 2005 and is currently in the council-approved Annual Construction Plan (ACP) and council-approved Six-Year Transportation Improvement Program (TIP). The role of 43rd Ave SE has been defined in the TE as a minor collector, which in the county system is a type of arterial road. The purpose of a minor collector, is “funneling traffic from local roads to the arterial network and providing a higher level of property access.” It is common to have minor collectors within both urban and rural residential neighborhoods. The current condition of 43rd Ave SE is preventing it from fulfilling its role as a collector. The purpose of the 43rd Ave SE project is to improve the existing road section to collector standards, reduce delay, improve safety and intersection operations, promote multi-modal mobility throughout the corridor, and improve the overall effectiveness of the county’s road system.
