Jyväskylä city council approves bypass plans for Highway 4 to ease traffic congestion

Traffic congestion along Highway 4 is a common issue, particularly near Vaajakoski, just before Jyväskylä. To alleviate the area’s traffic, plans for a bypass have been in the works for several years. On Monday, construction plans received a significant push forward when the Jyväskylä city council approved changes to land use zoning between Haapalahti and Ruokosaari. This decision enables the Finnish Transport Infrastructure Agency and regional development centers to advance the proposed plans for Highway 4.

The Vaajakoski bypass would span approximately three kilometers and is designed to enhance safety and reduce congestion. It would facilitate over 25,000 vehicles daily on busy days, with heavy traffic constituting 7 – 11%. Traffic volumes have surged nearly 20% over the past eight years, highlighting the need for this bypass.

Although the project has been discussed for over 13 years and an environmental impact assessment was completed a decade ago, it still requires state funding to move forward. The city is hopeful for a swift funding decision, emphasizing that the project represents a top priority for Jyväskylä’s interests.

Challenges remain, as securing funding is not guaranteed. The construction of a similar project, the Kirri–Tikkakoski section of Highway 4, took almost 30 years to complete. However, the current timelines are expected to be shorter since Highway 4 is part of Europe’s TEN-T transport network, which Finland has committed to implementing by 2030.

The bypass project is estimated to cost around €225 million. While state funding will cover the highway costs, Jyväskylä will incur significant expenses related to the integration of the new bypass with the city’s street network, likely exceeding €10 million. Moreover, environmental concerns have arisen regarding the project, prompting revisions to include habitats for flying squirrels.
