Project Description

The 2020 West Illinois Multimodal Transportation Study examined the feasibility and cost of reconstructing the Meridian/Illinois traffic signal as a single lane roundabout rather than the City re-investing in a new ADA-compliant traffic signal. The study documents that as a traffic signal, the intersection will degrade to an overall LOS E for vehicular operations with the westbound turn lane degrading to LOS F, but the intersection would improve to LOS B overall as a roundabout with the westbound to southbound movement improving to LOS C. In July 2020, Bellingham submitted grant applications to WSDOT for Pedestrian & Bicycle Safety improvements for the west half of W. Illinois Street (Lynn St - Meridian St) and Safe Route to School improvements for the east half of W. Illinois Street (Sunset Dr - Meridian St). If WSDOT grants are secured, then construction of sidewalks and bicycle lanes on West Illinois could occur in summer 2022, but these grants do not include the Meridian/Illinois intersection. Bike lanes on the Meridian-Girard corridor (Squalicum Pkwy - Young St) are planned with local funding in 2021 and TIB grant funding to reconstruct the traffic signal as a roundabout in 2021 would both improve intersection operations and complement the all of planned improvements to W. Illinois Street and the Meridian-Girard corridor.
