Welcome to the I-395/Route 9 Transportation Study Website!

MaineDOT and the Federal Highway Administration (FHWA)
are conducting this study to:

  1. Improve regional system linkage
  2. Improve safety
  3. Improve the current and future flow of traffic and the shipment of goods between I-395
    and Route 9
  4. Avoid and minimize adverse impacts to natural, social, cultural, and economic resources and features

It is envisioned that the results would be the construction of a new two-lane road from I-395 to Route 9 to the east of East Eddington or improvements to existing roads. If a new two-lane road is constructed, it would be a limited-access road crossing over or under the intersecting streets. The only exception could be a new interchange with Route 1A.

MaineDOT and the FHWA are preparing two primary items:

To help understand these items and preparing them, the U.S. Army Corps of Engineers has published Information on applying for permits for work in waterways or wetlands and a handbook providing guidance for the preparation of these two items at the same time.

I-395/Route 9 Transportation Study Draft Environmental Impact Statement and Section 404 Permit Application

MaineDOT and the Federal Highway Administration (FHWA) have released the Draft Environmental Impact Statement (DEIS)/Clean Water Act Section 404 Permit Application for the I-395/Route 9 Transportation Study for review and comment.

This DEIS/Clean Water Act Section 404 Permit Application examines the potential impacts of the “no-build” alternative and three “build” alternatives developed to satisfy the study purpose and needs. The purpose of this DEIS/Section 404 Permit application is to provide a full accounting of the potential impacts to the natural, social, and atmospheric environments and transportation system. It serves as the primary document to facilitate review of the project by federal, state, local agencies as well as the general public.

After careful consideration of all the alternatives, MaineDOT and FHWA identified Alternative 2B-2 as the preferred alternative because they believe it best satisfies the study purpose and needs, it fulfills their mission and responsibilities, and it has the least adverse impact.

As part of the review, MaineDOT and FHWA invite comments on its decision to identify Alternative 2B-2 as its preferred alternative. Comments on this and supporting information are due by May 15, 2012.

In order to informally discuss the project and this decision, an open house for the project will be held at the Brewer Auditorium located at 318 Wilson Street in Brewer, on Wednesday April 4th from 3 PM to 8 PM.

The open house will include several booths to be staffed with experts to answer the public’s questions about the study, environmental and property issues, as well as the designs. There will be large format displays of the three alternative routes available for viewing, as well as other detailed information.  The Army Corps of Engineers will attend, along with the Federal Highway Administration and MaineDOT.

The formal public hearing will be held in early May.  Members of the public can also provide their input during that meeting.

To help understand some of the potential changes in noise described in the DEIS, please see the diagram for a summary of common sounds and there decibel levels.

Section 404 of the Clean Water Act Permit
MaineDOT submited a permit application in accordance with Section 404 of the Clean Water Act to the U.S. Army Corps of Engineers. Section 404 of the Clean Water Act requires a permit for the discharge of dredged and fill material into Waters of the U.S, including wetlands. In response to the permit application, the U.S. Army Corps of Engineers issued their public notice soliciting comments on the project and range of issues addressed in the Draft EIS / Section 404 Permit Application supporting information.
