Making transit better
in North and Central Portland

North Central
Detailed map pdf

The North/Central Service Enhancement Plan is a future vision for transit service in North Portland, Northwest Portland, Northeast Portland west of I-205, Southeast Portland west of I-205 and north of Division, and downtown.

We developed this new vision using public input gathered through surveys, focus groups, public forums and community meetings, and using data about existing and future population growth, employment trends and transportation patterns. The result is a vision that calls for two new bus lines that would strengthen the transit network for all riders, multiple changes to existing bus routes to allow access to more destinations, improved frequency and expanded hours of service on select bus lines, and new community/job connectors to provide transit service in areas that don’t make sense for traditional bus or MAX.

Vision for Transit in the Future

The sections below describe the specific improvements in the vision that will make it easier for North and Central Portlanders to get around on transit.

Making it easier to access transit

The vision calls for two new bus lines and more changes to existing bus lines. These changes will provide new service coverage and new connections in the following places:

Delta Park Center on N Hayden Meadows Drive

There are multiple businesses and shopping centers in this area and many people have told us that they would like to access this area by transit. The vision calls for 6-Martin Luther King Jr Boulevard to provide new service coverage here.

Rivergate and the Columbia Corridor

There are thousands of jobs spread out along the Columbia Corridor and many people have asked us to make it easier to access them via transit. This vision calls for more frequency on 11-Rivergate/Marine Dr and a substantial extension of the line east to Parkrose/Sumner Transit Center, where it will make connections with several bus lines that serve East Portland and Gresham.

Swan Island

This vision includes replacing 85-Swan Island with 70-12th. 70-12th is a cross-town line that runs more frequently, later in the evening, on weekends, and connects to a substantial number of bus lines along its route from Milwaukie.

North, Northeast, and Southeast Portland neighborhoods

This vision includes changing the routing of several existing bus lines that together will strengthen the bus network throughout Northeast Portland and provide access to many more people.

A new bus line (shown on the map as line “Z”)

Will provide service connecting Parkrose/Sumner Transit Center to downtown Portland via NE Prescott, NE 33rd, NE Alberta, NE MLK and the Steel Bridge.

71-60th/122nd Ave

Routing will change in the Cully neighborhood and will provide new service coverage on NE Cully

Boulevard. It will connect to Parkrose/Sumner Transit Center via NE Killingsworth.


Will shift from NE 24th to NE 33rd Avenue and will continue to run to and from downtown Portland.

A new bus line (shown on the map as line “Y”)

Will provide service on NE 24th and NE 27th Ave and connect to new service on NE/SE 20th Ave. This will create a new continuous north-south transit connection between NE Portland and Sellwood connecting many neighborhoods and neighborhood commercial centers in both NE and SE Portland.

Northwest Portland neighborhoods

This vision includes extensions of two bus lines into Northwest Portland to help increase access to transit for this very vibrant and transit-oriented part of our region.

10-Harold St

Will be extended from its existing route in SE Portland to provide new service in the northern part of the Pearl District and the alphabet district, via NW 12th, NW 14th, and NW Raleigh.


Will be extended from its existing route in NE Portland across the Fremont Bridge and connect to Providence Park via NW 18th and NW 19th.

Passing Through Flexible Federal Funds for Transit Service

There are areas in our region where the businesses and/or homes are so scattered or use so much land that there aren’t enough people within walking distance of bus stops to cost-effectively provide fixed-route bus service. In other cases there aren’t enough roadway connections to let people walk to and from bus stops. Unfortunately, these areas are often the same places where housing is more affordable or where there are well-paying, entry-level jobs. However, even when TriMet cannot operate fixed route bus service, it has a long history of helping communities by passing on federal funds to other organizations to operate their own smaller, flexible services that can meet the unique needs of residents and employees. Connector services like these currently operate in Hillsboro, Forest Grove, and Tualatin. In the North/Central area, opportunities for shuttle services include the areas listed below. These areas are shown on the map as “community/jobs connector service areas.”

Airport Way Industrial Area

A community/jobs connector service could provide transit access to businesses along streets such as NE Cornfoot and NE Alderwood.

East Columbia and Bridgeton neighborhoods

A community/jobs connector service could connect residences along NE 13th Ave and Marine Drive to TriMet’s fixed-route system.

Hayden Island neighborhood

A community/jobs connector service could connect residences in the Hayden Island neighborhood to TriMet’s fixed-route system.

Northwest Heights neighborhood

A community/jobs connector service could connect residences along Miller Road to TriMet’s fixed-route system.

Walking to your local bus stop or MAX station

Most TriMet riders begin and end their trip by walking (or rolling using a mobility device). TriMet doesn’t control where sidewalks and crossings are built, but we work with local cities, counties and the Oregon Department of Transportation to encourage construction of sidewalks and safe crossings where people can use them to get to bus stops. TriMet created a Pedestrian Network Analysis

( to help prioritize where to make sidewalk and crossing investments, based on needs and opportunities including higher ridership locations.

Providing more freedom and flexibility in how people can use transit

Freedom and flexibility to a transit rider are determined by the frequency of service provided, the hours of the day the service is provided and the days of the week the service is provided.

More frequency

Many of our bus lines today function well, but would be more useful to riders with more frequency. As part of our standard practice, we regularly look at adding trips on all of our existing bus lines when we see that the number of people riding the bus exceeds the capacity that we currently provide. Because demand is lower during the midday, early morning, late evening, and weekends, we provide less service during those days on many lines. However, we envision additional frequency for these lines:

11-Rivergate/Marine Dr.

Line 11 currently provides service along Columbia Boulevard, Lombard, and Marine Drive in the Rivergate Industrial Area. This is an important line for providing access to jobs. However, many of the jobs in this area start and end at times when the Line 11 does not currently run. This vision includes adding more trips to this line during times that it doesn’t currently run so that more people can get to and from their jobs on transit. (Also, as is described above, the vision for Line 11 is to extend it eastward to the Parkrose/Sumner Transit Center.)

15-Belmont/NW 23rd in the NW Industrial District

The Northwest Industrial Area end of Line 15 currently has less frequent service than the main part of the line on Belmont and NW 23rd Avenue. In order to help improve access to jobs in the NW Industrial District, this vision includes increasing the frequency of service on that portion of Line 15.

16-Front Ave/St. Helens Road

Line 16 provides a fast trip for riders between St. Johns, Linnton, and downtown Portland. This vision includes more frequent service on this line to help strengthen this important travel option.


This line provides a key link between many neighborhoods and destinations throughout North and Central Portland and connects Beaverton to Gresham. Line 20 today provides over 10,000 rides on a typical weekday on its full length. This vision includes upgrading this line to a full Frequent Service line.


Line 77 connects Troutdale to downtown Portland and provides service to important commercial areas in the Hollywood area, the Lloyd District, the Pearl District and in the alphabet district of Northwest Portland. As the population in these areas increase, so does the demand for transit service. This vision includes continuing to add more frequency to this line.

More weekend service

Most, but not all, of the bus lines in the North/Central area currently run 7 days per week. This vision includes adding weekend service to lines 24-Fremont, 16-Front Ave/St. Helens Rd and 63-Washington Park/Arlington Heights so that more people can get where they need to go on Saturdays and Sundays.

Service in the early morning and late night

Many people have told us that they want to be able to ride transit in the late night and early morning hours. This vision includes adding later and earlier service on lines that together serve the majority of North and Central Portland, including 4- Division/Fessenden, 15-Belmont/NW 23rd, 20-Burnside/Stark, 72-Killingsworth/82nd and 75-Lombard/Cesar Chavez.

Making transit more attractive and efficient

TriMet will continue to work with cities, counties and the Oregon Department of Transportation to identify opportunities for transit signal priority and other construction and service improvements to help our bus riders get to their destinations quickly, efficiently and with minimal delay. Opportunities could include intersection improvements, limited stop services, and even more significant bus line projects. TriMet will generally focus on the highest ridership and most frequent lines for these kinds of improvements to maximize the number of people who benefit from our efforts.
