Introduction
The designation E31 refers to a European route that traverses part of the Netherlands. It is one of the trans-European corridors established to facilitate road transport across national borders. The route connects key urban centres, supports regional economies, and forms an integral part of the broader European road network. The E31 is primarily an autoroute-class road that offers high-capacity, high-speed travel, and its management involves coordination between national and regional authorities.
In the context of European road infrastructure, the E31 exemplifies the principles of interoperability, standardisation, and strategic connectivity. Its development reflects historical trends in transportation planning, the growth of automobile traffic, and the need for efficient freight movement. This article provides a detailed overview of the E31, covering its historical evolution, route characteristics, economic significance, safety considerations, environmental impact, future plans, and related concepts within the European transport system.
History and Background
Origins of the European Route Numbering System
The European route numbering system was established by the United Nations Economic Commission for Europe (UNECE) in 1950 as part of a broader effort to create a coherent network of roads across the continent. The goal was to enhance international mobility, promote trade, and support post-war reconstruction. Initially, the system used a hierarchical numbering scheme with single- and double-digit numbers for primary routes and three-digit numbers for supplementary roads.
Over subsequent decades, the system was refined to accommodate the rapid expansion of road networks and changing transportation needs. The European route network now includes thousands of kilometres of roads, ranging from rural highways to major motorways. Each route is designated by a letter (E) followed by a number, with odd numbers generally assigned to north-south routes and even numbers to east-west routes.
Development of the E31
The E31 was incorporated into the European route network as part of the 1960 revisions. Its establishment was driven by the necessity to link the port city of Rotterdam with inland regions and to provide a continuous corridor for freight and passenger traffic. Prior to its designation as a European route, the road that forms the core of the E31 existed as a national highway managed by Dutch authorities.
The official designation of E31 was formalised in 1975, following a series of agreements between the Netherlands and the UNECE. Since then, the route has undergone continuous upgrades to meet European safety standards and capacity requirements. The changes have included widening of lanes, implementation of controlled access sections, and integration of advanced traffic management systems.
Route Description
Overall Path
The E31 begins at the junction with the Dutch A20 near the city of Rotterdam and extends southward, terminating at the intersection with the A12 near the town of Zevenaar. The total length of the route is approximately 140 kilometres. Throughout its course, the E31 follows a largely east-west orientation, passing through urban, suburban, and rural landscapes.
The route is predominantly a dual carriageway, featuring two lanes in each direction separated by a central median. In certain sections, especially near major cities, the road expands to four or six lanes to accommodate high traffic volumes. The E31 also incorporates grade-separated interchanges at key junctions, ensuring uninterrupted flow and reducing collision risks.

- Wassenaar – Located near the western terminus, the area benefits from proximity to major motorways.
- Zevenaar – The northern terminus intersects with the A12, linking the route to broader national and international corridors.
Infrastructure Characteristics
The E31 is constructed to comply with European motorway standards, including lane widths of 3.5 metres, shoulder widths of 2.5 metres, and adequate curvature radii for high-speed travel. Safety features such as guardrails, median barriers, and clearly marked signage are integral components of the route’s design. The road’s maintenance is overseen by the Dutch Ministry of Infrastructure and Water Management, with support from local authorities.
In addition to its structural elements, the E31 incorporates modern traffic monitoring systems. These systems collect data on vehicle flow, speed, and incident reporting, allowing for proactive traffic management and rapid response to accidents or congestion.
Traffic and Usage
The E31 serves as a vital corridor for both freight and passenger vehicles. Its role in freight transport is underscored by the proximity to Rotterdam’s port facilities, making it a preferred route for trucks carrying goods to inland destinations.
