99WI18 interim Corridor Strategy
' 1 Executive Summary
What Is Corridor Planning and Why Is It Being Done
The Oregon Department of Transportation is developing plans for 31 transportation '
corridors identified in the Oregon Transportation Plan(OTP)as being of statewide or
interstate importance. w ;
A corridor pian is a long-range program for managing and improving transportation
facilities and services to meet the needs for moving people and goods.A key element of
corridor planning is consideration of the linkage between land use and transportation t`=;
needs. 2,
i Highway 99W and Highway 18 extend 75 miles beriveen Portland and Lincoln City,serving
# accessibility among growing cities and rural communities,freight movement,tourism,and ,
commute and recreational travel.The benefits of long-range planning in this corridor '-
include(a)resolution of planning issues,(b)preservation of transportation rights-of-way,
(c)protection of transportation investments,and(d)cwperation among diverse
organizations to implement projects and services. ''
s The Oregon Transportation Plan establishes the general policies and planning direction for tsf
tthe development of corridor plans.It also responds to related modal plans for freight1 .
movement,rail service,aviation,pedestrian/bicycle,public transportation,and safety that ,Y �,•,.
have been adopted.Corridor plans assist in the development of transportation projects for
implementation through the Statewide Transportatior.Improvement Plan(STIP). f"
Comdor planning is organized into three

This interim corridor strategy plan addresses the operation,preservation,and improvement
of transportation facilities in the Highway 99W/18 corridor.It covers a 20-year planning
period,building upon federal,state,and local transportation and land use policies and
rplans.The involvement of residents,users,and other participants has resulted in extensive
'inputto the strategy plan.This strategy will guide subsequent development of the Corridor
Plan and Refinement Plans,and serve as the basis for selection of individual improvement €
.projects and implementation of new or expanded transportation services.

1. Corridor Overview
.The corridor extends along Highwav 99tH from I-5(Exit 294)in Portland to McDougal
's
Corner near Dayton,and along Highway 18 west to Highway 101 on the Oregon Coast.It is
designated as a Corridor of Statewide Importance in the OTP and as part o"the National
Highway System.Railroads in the corridor extend from Portland to Fort Hill,but do not
reach the coast.The corridor serves the metropolitan areas southwest of Portland, w '
connecting to communities in the Yamhill Valley and west along the Salmon River,as €,
shown on Figure ES-1.The corridor provides commuter access to cities along the route and
is a primary link to the Oregon Coast from both Portland and Salem. € ,.
,a €
Daily traffic volumes on the highway currently range from about 6,000 vehicles per day
x
(vpd)near Highway 101 to 53,000 vpd in Tigard near I-S.Future volumes in these areas are ! ',IR
predicted to range from about 10,000 vpd to the west to more than 80,000 vpd in Tigard. k
Trucks currently comprise 6 to 8 percent of traffic volume in the corridor(940 to 1,740 vpd). '
.: .Public transit consists of bus service in the Portland metropolitan area and dial-a-ride
service elsewhere.No passenger rail service currently operates in the corridor,but studies
have been conducted to investigate commuter rail feasibility and potential connections to
.the Portland area light rail system.Ashort-line railroad operates in the corridor as far west
as Fort Hill,with connections to Portland and to Albany.Public airports are located in
McMinnville,Newberg,and Sheridan,but there is no scheduled commercial air service in
these communities.Portland International Airport is located about 15 miles north of the
corridor terminus. y `
Congested traffic operations develop on a recurring basis during weekday commute hours
in the Portland metropolitan area and outlying cities,and throughout the corridor on € ,
"3
summer weekends and holidays.Two gambling casinos have recently opened in the
corridor,adding to the tourist and recreational draw. t`
Accident experience along the corridor is generally consistent with statewide averages for
the various urban and rural segments,but fatality rates exceed statewide averages on € € €
Highway 18 west of McMinnville and in the urban areas along Highway 99W-The lack of
astir � .sidewalks,.v discourages pedestrian a_
d bicycle activity.
2. Major Issues
The H h away 99 /Io. corridor
� .,.•..,mac. c>a wide syai.um of landscapes,including the
coastal estuary,the Coast Range,the rich farmlands of the Yamhill.Willamette,and € r
"Tualatin Valleys,small rural communities,and cities ranging to the state's largest a
metropolitan area.Given this diversity of interests,an extensive menu of potential actions
was mentioned by participants in the public involvement program.Most frequently cited
were problems of congestion,safety,lack of commute alternatives,need for bypass routes
difficulties of access,and uncertainty'of funding for improvements.The range of issues i,,', €
highlighted briefly below,for topics specified in the OTP.

Transportation Balance
Transportation in the corridor is served by a variety of passenger and freight modes,but " k
commuter travel continues to be donunated by the private automobile.Transportation ��
:.plans in the urban areas emphasize the need to address congestion through measures that t
„y reduce the relative demand for single-occupant travel,simultaneously expanding commute [
options such as carpooling,transit,bicycling,and walking. fY;
Implementation of commuter rail service or connections to the light rail system could prove
to be a viable commute option in this corridor at a future time. lr`•*.„
Improved freight mobility in the corridor could be achieved with projects to control access,
reduce delays,add passing and track climbing lanes,and reconstruct curves along the
highway.Improved railroad transportation could be provided by upgrading tracks to allow
higher operating speeds.
Regional Connectivity
Connections among the communities served by Highway 99W/18 are vital to the local and
.state economy.The highway serves as a major arterial route for commuters,tourists,local :r
users,and freight movement.In many communities,it also is the focus of commercial r is
activity,with the result that conflicts develop between the functions of through movement ,
and local access. r�-i
VO
Growth in population,tourism,and employment is increasing travel demand in the
jcorridor,adversely affecting travel times for both commute and recreational purpbses.
Measures that protect or enhance the capacity of the corridor will be required to maintain r i r'i "^b
efficient connections.These measures could include widening,added lanes for turning, u
passing,or truck climbing,conversion to full access control with interchanges,development E '"'i't'k
of bypasses,and access management programs. r 'r
Highway Congestion
ti ii'�itr`
In the Portland metropolitan area,a combination of actions will be required to address
traffic congestion.First,aggressive programs to manage transportation demand are
- available to shift travel to other modes through carpool matching,transit service expansion,
park-and-ride facilities,employer trip reduction programs,and elimination of free parking ''h +'
for commuters..Transportation system management measures also will be pursued,
-t' consisting of signal coordination,addition of turning lanes,raised medians,shared v �r
driveways,ana access management.
r
As these measures succeed,the subsequent needs to widen the highway may be reduced.A
r
. travel demand of up to six lanes is projected on Highway 99LV north of Sherwood,but there '
i are significant constraints within Tigard including the cost of right-of-way,impacts on
buildings and histone structures air quality and noise concerns,and land use objectives. p
in the rural areas four lanes may be necessary to accommodate future travel demands. s
Grade-separated interchanges could be developed at junctions with other highways and t
arterial streets..Opportunities for widening are limited by natural constraints in the Van i
Dozer Corridor and along the Salmon River,including habitat for sensitive species,
landslide areas,parkland,wetlands,and topographic limitations. ' "1

Safety i
j Safety performance of the corridor could deteriorate as volumes of through and turning
traffic grow,unless accident countermeasures are instituted.Safety improvements can be
jaccomplished with programs to modify intersections,add shoulders,grade-separate
junctions,rebuild tight curves,control access,and create a multi-lane divided highway.A
detailed analysis of accident patterns will reveal appropriate countermeasures to be
targeted for implementation in the short term.
Transportation Impacts
The natural environments through which the corridor passes are considered assets to the
s t' region.Transportation impacts that impinge on the environmental quality of the corridor
t should be restricted.Measures to avoid or mitigate adverse impacts will be required. €
Improvement projects also provide opportunities to correct past environmental damage. m
Implementing programs that emphasize alternative modes could contribute to reduced
growth of vehicle-miles of travel and promote energy efficiency.These efforts will
complement emerging land use principles that emphasize pedestrian-friendly and transit-
oriented development.

3. Corridor Strategy 4
The corridor strategy for Highway 99W/18 consists of a series of actions that respond to its
{, vital role in serving commute and recreational travel and freight movement,and to the
numerous constraints associated with corridor improvements.The following measures are
envisioned.
Transportation Balance
+ Pursue transportation demand and system management strategies as a first course in rk�
-' addressing future needs. a,
Develop support facilities for transit,carpooling,and the use of nonrnotorized modes.'
Retain the railroad as an effective means of freight transport,and investigate a opportunities for for commuter rail service in the corridor.

What's!Next
Following endorsement of the Interim Corridor Strategy by jurisdictions along the corridor,
the Corridor Plan will be developed.It will strive to preserve and enhance the corridor
through close coordination with local land use and transportation plans.
k�The Corridor Strategy identifies a wide range of actions to be implemented by many
agencies and service providers.In some areas,Refinement F1ar6 will provide more detailed
analysis.Additional public involvement is anticipated in future work phases.These inputs `yr '
will be reflected in the selection of future projects and services.Decisions concerning
;priorities,trade-offs,and funding also will influence implementation of projects in the , `E "
