Current Status

This project is in the early design phase. Construction is scheduled to begin in spring 2014.

A public open house about the project occured on Oct. 24, 2012. A summary of the comments received at the open house, including responses from ODOT is now available.

 

Project Summary

The Oregon Department of Transportation (ODOT) has made several improvements to the interchange at exit 17 (NE 257th Avenue and Marine Drive) on Interstate 84 in Troutdale over the last few years—the most recent of which was completed in 2011.

Design work is now under way on another improvement project at this freeway interchange, this time focusing on the Marine Drive section. This project will:

  • Widen Marine Drive between the two frontage roads to allow for two-way traffic, so vehicles exiting I-84 eastbound can turn directly on to Marine Drive instead of travelling all the way around on the frontage roads
  • Remove the existing I-84 overpass bridges at Marine Drive and replace them with a new bridge that is longer to accommodate the widening of Marine Drive and taller to allow for the passage of vehicles up to 17 feet, 4 inches
  • The intersection of Marine Drive and the north Frontage Road will also be changed to accommodate the new two-way traffic configuration. The existing free-flow right turn lane from the north Frontage Road onto Marine Drive northbound will be moved to the signalized intersection to increase drivers’ visibility as they first yield and then merge with the new northbound traffic on Marine Drive
  • Provide a dedicated left turn lane on the north Frontage Road for vehicles turning south onto Marine Drive
  • Add a marked bike lane and sidewalk to the west side of Marine Drive under I-84
Why does the free-flow right turn lane from the north Frontage Road onto Marine Drive have to be removed?
This project will widen Marine Drive under I-84 to allow vehicles to travel in both directions. This means motorists exiting I-84 eastbound at exit 17 will be able to turn left onto Marine Drive from the end of the exit ramp, instead of looping around on the frontage roads. As a result, motorists turning right from the north Frontage Road onto Marine Drive will have to watch out for, and yield to, oncoming vehicles before they can make their turn, which they don’t currently have to do.
 
Keeping the free-flow right turn lane would make it more difficult for motorists to merge safely with the new traffic on Marine Drive northbound coming from the I-84 eastbound off-ramp, especially because they’re not used to doing it. To help improve safety and operations, the right turn lane will be moved closer to the signalized intersection and motorists will be required to yield to oncoming traffic on Marine Drive before making their turn.

Project Funding

This project is being paid for primarily by Oregon House Bill 2001, also known as the Jobs and Transportation Act (JTA), along with some federal transportation funding. 
 

Previous Projects

This project is being developed as part of a larger partnership effort between ODOT, the Port of Portland the City of Troutdale to improve the interchange.

2009: A project funded by ODOT, the Port of Portland, the City of Troutdale and the federal stimulus program added an additional turn lane for traffic headed east on the south Frontage Road to 257th Avenue/NW Graham Road.
 
2011: State JTA funds were used to widen the I-84 eastbound exit ramp and improve the intersection with Marine Drive, add a third lane to the south Frontage Road, and improve the intersection at the I-84 westbound exit ramp and NW Graham Road, including adding a third lane to the north Frontage Road.
 

Project Purpose & Need

The I-84 Troutdale interchange (exit 17) is an important freeway connection to many businesses at the eastern end of the Columbia industrial corridor, as well as Troutdale’s residents and visitors. A recently constructed FedEx Ground distribution facility located on industrial land owned by the Port of Portland north of the interchange and the potential for added commercial growth in this area are expected to bring more traffic.
 
This project, and the two projects that have already been completed, will help improve operations and safety at this interchange, and improve freight access between I-84 and the industrial properties to the north.

 

2011 Interchange Area Management Plan

In 2010-11, ODOT partnered with the City of Troutdale to develop and Interchange Area Management Plan (IAMP) to plan for the future of the Interstate 84 (exit 17) interchange area. The goal of this effort was to ensure that the improved traffic flow, access, and mobility from the recent and upcoming JTA construction projects is maintained as long as possible.

ODOT formed a Project Advisory Committee (PAC) in 2010 representing various stakeholder interests and community members to guide the development of the plan. After nearly a year of work, the PAC presented the draft plan to the Oregon Transportation Commission for review and action. The Commission unanimously approved the plan at its meeting in July 2011.

Get Involved

A public open house about the project was held on Oct. 24, 2012 at the Holiday Inn Express off of the South Frontage Road. ODOT staff plan to provide information about the project at a number of local community events in 2013 and will host another public open house before construction starts.
