Concepts

Welcome to the concepts page for the I-84 Danbury Project. This page includes all concepts that are being developed for the I-84 corridor between Interchanges 1 and 8. As concepts are developed, they will be added to this page.

Please review a concept by clicking the Learn More button. Concepts can also be filtered by clicking on the green mainline button, blue interchange button, or gray non-highway button below.

Concept 1

Concept 1 seeks to create lane continuity, eliminate left-hand exit ramps, and, where possible, improve horizontal curvature and vertical geometry. This concept endeavors to maintain the current alignment of I-84 and stay within the existing right-of-way to the greatest extent possible.

Concept 1: Lane add - Mainline

Concept 1 seeks to create lane continuity, eliminate left-hand exit ramps, and, where possible, improve horizontal curvature and vertical geometry. This concept endeavors to maintain the current alignment of I-84 and stay within the existing right-of-way to the greatest extent possible. The primary component of this concept is the addition of travel lanes to eastbound and westbound I-84 to provide at least three lanes of travel in each direction. Improvements are only proposed at Interchanges 3 and 7 on I-84. No improvements are proposed at the remaining interchanges on I-84.
