1. INTRODUCTION
This report is intended to provide a set of coordinated transportation management strategies used
to manage the temporary work zone impacts of US101: Youngs Bay Bridge - Neptune Drive.
TMP Goals
• To communicate the subject project construction footprint.
• To maximize work zone safety for construction workers and travelling public.
• To communicate and minimize work zone delay impact factors for freight mobility.
• To convey the work zone traffic control means and methods of construction.
• To manage intra/inter agency early project coordination.
• To indicate the types of notifications and communications planned to involve the public.
2. PROJECT DESCRIPTION
The primary purpose of this project is to resurface/restore/rehabilitate (3R) the pavement on US
101 from MP 5.31 to MP 6.84. MP 5.31 is the southern end of New Youngs Bay Bridge and the start
of the New Youngs Bay Bridge causeway and MP 6.84 is a pavement joint on the SW leg of the T
intersection between US 101 and Neptune Ave.
Because this is a 3R project, additional mandatory design features include ADA/Sidewalk Ramp
upgrades and existing guardrail upgrades (HDM 6.4.10).

Traffic Control Narrative
There are two segments on this project that will require different forms of traffic control. MP
5.31 to 6.42 is a constrained 2-lane causeway section. There is limited space for traffic and the
work zone to share. Lane closure restrictions in this section are also restrictive to limited
nighttime hours only. There will be two alternatives for completing work along this section. A
nighttime detour route will be provided which will allow a full closure of the causeway section.
This closure will be a benefit for both work zone safety and for faster completion of the paving
work. Single lane closures utilizing flaggers will be the alternate option for this section. A
combination of the two methods is likely and will provide the contractor the opportunity to
select the best method. MP 6.42 to 6.83 is a section that consists of 2 through lanes but also has
turn lanes, signals, and a driveway access. This section will be paved using single lane closures at
night. Flaggers will be required to control traffic during lane closures and signal shut-offs. There
will also be right turn lane widening on US101 SB at Harbor Dr. A temporary closure of the
existing southbound right turn lane will be required to accommodate the widening work. Work
will be staged as follows:
Stage I: This stage will consist of widening work for the southbound US101 right turn lane at
Harbor Dr, ADA level landing construction, and signal work. The north leg of the intersection at
Harbor Dr does not currently have a crosswalk. A crosswalk will be added at this location. The
addition of a crosswalk will also enable the closure of other crosswalks for subsequent stages.
The southbound US101 right turn lane will be closed during this stage to allow for the
construction of a widened lane.
Stage II: During Stage II the south leg of the intersection of US101 at Harbor Dr will be
constructed. ADA level landings will be constructed along with signal work during this stage.
Stage III: The north leg of the intersection of US101 at Neptune Dr will be constructed during
this stage. ADA level landings will be constructed along with signal work.
Stage IV: The south leg of the intersection of US101 at Neptune Dr will be constructed during
this stage. ADA level landings and sidewalk will be constructed along with signal work. During
this stage, the right turn lane on Neptune Dr will be closed to allow space for construction and
the TPAR.
Paving work and guardrail replacement may occur concurrently with the staged work at the
intersections or it may happen at another time. Most of these components of the work are
independent of one another with the exception of coordinating paving work to tie-in with the
work at the intersections.

Pedestrian & Bicycle Mobility
No sidewalk exists on this section of Oregon Coast Highway (US101). Pedestrians will be
expected to use the existing facilities except in active work areas, where an appropriate TPAR
will be provided according to the stage of work. Concrete pedestrian landings will be added at
the intersections of Harbor Dr and Neptune Dr to meet ADA requirements for access to the push
buttons. During paving work, pedestrians and cyclists will be accommodated by using flaggers to
stop and hold traffic. During the US101 causeway closure, a pedestrian transport vehicle will be
on site to transport any pedestrians or cyclists needing to use the highway. Bicycles will need to
use the same travel lane as other vehicles and will be accommodated using standard “Bikes on
Roadway” signage.
Stage I: The crosswalk on the north side of the Harbor Drive intersection will be closed during
this stage. Pedestrians will not be able to use the southbound US101 shoulder during this stage.
Pedestrians will be directed to cross to the east side of US101. A temporary walk will be
constructed around the ADA landing work on the east side of the highway.
Stage II: The crosswalk on the south side of the Harbor Drive intersection will be closed during
this stage. A temporary walk will be constructed around the ADA landing work on the east side
of the highway.
Stage III: The crosswalk on the north side of the Neptune Drive intersection will be closed during
this stage. There is sufficient shoulder space available at this intersection to allow pedestrians to
pass through without constructing a separate walkway.
Stage IV: The crosswalk on the south side of the Neptune Drive intersection will be closed during
this stage. The sidewalk along the south side of Neptune Drive will be kept open by using a
temporary curb ramp. Pedestrians will use the closed right turn lane and shoulder space as the
TPAR.
Freight Mobility
This section of the Oregon Coast Highway (US101) is a Black Route on the MCTD Freight Mobility
Daylight Width Map. This route allows load up to 14’ wide by annual trip permits and sees
extensive use for loads greater than 14’ wide by single trip permit.
Standard Truck Freight Mobility will be maintained for US101 throughout the project
construction. Mobility for over-dimensional loads up to 14 feet wide will be maintained
throughout the project as well. Mobility for over-dimensional loads wider than 14 feet would
benefit with the use of advance notification. Without advance notification, longer clearance
delays can be expected.

Detour
Paving work on US101 from MP 5.31 to 6.42 will be completed using a full road closure of the
causeway and New Youngs Bay Bridge. Traffic will be detoured using state highways US101
Business and OR202. Access will be cut off at the north end at the existing roundabout north of
the New Youngs Bay Bridge. All southbound traffic will be required use OR202 (Marine Dr).
OR202 leads to US101 business where traffic will use the Old Youngs Bay Bridge. US101 Business
connects back to US101 either at Fort Stevens Hwy Spur or Marlin Ave. All northbound traffic
will be required to use US101 Business which will connect to OR202 and US101 back at the
roundabout north of the New Youngs Bay Bridge.
Seasonal Work
Oregon Coast Highway (US101) sees higher traffic volumes during the summer months due to its
connections to coastal destinations and summer recreational areas. These volumes are
accounted for in the lane restriction analysis and this is the reason lane closures will only be
allowed at night. Also, due to the coastal weather patterns, prime construction season coincides
with peak tourist season.
Environmental Factors
This project triggers stormwater treatment which will be treated offsite near Perkins Lane. The
project turn lane encroaches on a wetland in front of Walgreens that will need to be delineated
and mitigation for the wetland will be at a local wetland bank approximately $20000. The
Project will require an Archeological pedestrian survey with an estimate of $50000. Public
outreach will be needed.
Sediment Control BMPs will be placed behind the work areas to control sediment and
construction debris from entering the wetlands. Soil disturbed by construction will be reseeded
with a native seeding.
