 Project Overview

Lined with several different types of businesses and public transit, McLoughlin Boulevard (Oregon Highway 99E) between Naef Road and the Clackamas River Bridge carries 33,000 motorists on a given day and serves numerous bicyclists and pedestrians along this nearly two mile stretch.


The roadway, however, is falling apart under the asphalt in several locations. Road users experience a bumpy ride along the entire stretch of highway. There are five traffic signals in this area and they are not connected. This means, traffic does not flow efficiently. There are also several long sections without sidewalks at all, requiring pedestrians to walk on the shoulders of busy McLoughlin Boulevard.


ODOT has designed a project that will preserve the paved surface of SE McLoughlin Boulevard for years to come by repairing failing sections and repaving the road.


Project elements include:


Rebuilding sections of the road on OR 99E under the pavement up to 30 inches deep
Repaving the roadway on OR 99E between Naef Road and the Clackamas River Bridge
Connecting sidewalks in multiple locations – see below for details
Improving sub-standard ADA ramps in multiple locations
Striping bike lanes
Connecting the traffic signals to improve traffic flow  

Rebuilding Failing Sections of the Roadway 

ODOT identified multiple locations in the northbound and southbound directions of SE McLoughlin Boulevard where the roadway is crumbling beneath the asphalt. When construction is underway, workers will dig out the failing roadbed below the asphalt and rebuild the road surface.  


ODOT is planning to fill in the sidewalk gaps at the following locations. Some sidewalks will include planter strips, others will not due to the width available along the roadway.


Sidewalk Locations
North of Ina Avenue
Between Boardman Road and Ina Avenue
Between Hull and Meldrum Avenue
Between SE Mildred Street and SE Glen Echo
South of SE Glen Echo


 How Did ODOT Determine the Sidewalk Locations?


The $1 million funding for the sidewalks only meets a portion of the sidewalk need in the project area. For this reason, selection criteria have been developed to identify locations where sidewalks will provide the most benefit. Based on the objectives below, multiple locations were identified as priority locations for sidewalk in-fill.

Selection Criteria for Sidewalk Locations 

Ø     Pedestrian Safety. Some areas now require pedestrians to walk on the highway shoulder for a hard surface. The locations selected  provide sidewalks where no safe, hard surface exists. Some areas are without sidewalks but have flat asphalt pavement that provides an adequate walking surface. These areas will not include new sidewalks as part of this project.


Ø      Provide sidewalks to improve access to bus stops.


Ø      Improve the crossing over Boardman Creek.


Ø      Cost-Benefit. The following factors come into play in terms of the cost of sidewalk installation and the benefit that results:


o        Landscaped planter areas within the public right of way will generally not be landscaped. Citizens interested in landscaping in the sidewalks that have space for plantings can use ODOT’s adopt-a-landscape program.


o        Existing curbs retained. Generally, the existing curb location will be maintained where it currently exist to allow the savings to be used on more rather than less sidewalk.


o        Existing but substandard sidewalks (due to location or width) will be retained in order to focus on areas where no sidewalk currently exists.


o        Redevelopment sites. ODOT will not install  sidewalks where adjacent redevelopment is likely to occur and where there is a safe hard surface to provide access.


Other Important Factors


Ø      Tree preservation – The type of sidewalks in certain areas were selected to avoid removing existing trees. Only trees will be removed in the project limits because they have the potential of falling into the roadway.


Improving Traffic Signal Efficiency 


The traffic signals span this two mile section of SE McLoughlin Boulevard and do not function efficiently. Drivers may notice that they seem to stop at every signal. Interconnecting the traffic signals requires adding hardware and software to the traffic signals that will help improve traffic flow. When this work is complete, drivers will notice less stopping at every single traffic signal.


Construction Impacts 


Traffic Impacts:

  • Single lane closures and shoulder closures during the day

  • Paving work to occur at night when traffic volumes are lower 

  • Multiple lane closures at night

  • No closures on major holiday weekends

Please also read the weekly construction updates for traffic impacts, updated every Friday.
