Egan Drive - Vanderbilt Hill Road Continuous Green T Intersection

Project No. 0932054/SFHWY00524

Project Overview

What is the purpose of this project?

The Egan Drive and Vanderbilt Hill Road Intersection Improvement project aims to transform one of Juneau’s intersections into a safer, more efficient corridor. The project will implement a "Continuous Green T" design, which allows southbound traffic on Egan Drive to flow through the intersection without stopping for a red light. Drivers turning left from Vanderbilt Hill Road onto southbound Egan will be given their own protected lane to safely merge into traffic. By allowing one direction of the highway to move freely, the updated traffic signals can provide more green-light time for other turns, reducing delays for everyone.

What construction activities will take place?

Construction activities will include:

Installation and removal of construction signage
Reconstruction of medians
New signage, traffic pattern, and striping
Grading and paving

How will construction affect me?

Traffic control will include permanent construction signage, lane closures, reduced speed zones, and route detours.

Construction Update

Planned Construction Activities and Major Impacts

Vanderbilt Hill Road is closed as of May 27, 2026, and will remain closed for the duration of the project. All traffic must use the Glacier Highway detour described below. Please plan ahead and allow extra travel time.

Construction began May 27, 2026, and continue through August 30, 2026. Work will be completed in phases:

Phase 1 includes mobilization, the Vanderbilt Hill Road closure and detour, and new median work on Vanderbilt Hill Road and Egan Drive.
Phase 2 includes the new acceleration lane and widened left-turn lane on Egan Drive, paving, new signal timing, and intersection reopening before final project completion.

Traffic Control Plan and Impacts to Residents and Businesses

Motorists traveling to or from the Lemon Creek area will need to detour via Glacier Highway, using the following routes:
- Southbound from the Valley: Use the detour exit at the Sunny Point Intersection
- Northbound from Downtown: Use the detour exit at the Hospital Intersection
Expect a 45 MPH speed limit on Egan Drive for approximately one-quarter mile approaching the Vanderbilt intersection from both the north and south.
Fines are doubled in work zones. Please slow down, stay alert, and watch for crews in this area.

Current Construction Activities

For the week of June 22: Activities include placing barriers, installing BMP erosion control, grubbing and removing invasives, and installing pipe extension and Type-A inlets.
For the week of June 29: Activities include continued grubbing and milling for the new offset turn lane.
