PROJECT DESCRIPTION
This report evaluates the barrier rail replacement and approach guardrail requirement options for
the Carlsbad Boulevard Overhead and barrier and approach rail installation options for the
Encina Discharge Channel on Carlsbad Boulevard.
The Carlsbad Boulevard Overhead was originally
constructed in 1925, widened in 1929, and seismically
retrofitted in 2006. The bridge consists of a 5-span
simply supported reinforced concrete T-beam stmcture,
supported on portal frame bents, founded on spread
footings. The stmcture crosses two rail lines that are
owned by North County Transit District (NCTD). The
existing barrier rail is the original reinforced concrete
open railing and has been damaged due to vehicular
collisions and deterioration over the years. A 4-foot
sidewalk is located on the south side of the bridge.
Currently no approach railing exists at any of the barrier ends.
The Encina Discharge Channel is located on Carlsbad
Boulevard and spans the warm water discharge
channel for the Encina Power Station. This stmcture,
originally constructed in 1954, is a 2-span reinforced
concrete culvert. It currently has a chain-link fence as
the barrier at the edge of the stmcture located behind
5 feet of sidewalk on the east and 10 feet, 10 inches
of sidewalk on the west. Approach railing is not
present at any of the barrier ends.

Encina Discharge Channel, west side
APPROACH RAILING
The Carlsbad Boulevard Overhead is located at
the crest of a vertical curve on a tangent portion
of Carlsbad Boulevard. The stmcture is
approximately 51 feet wide with approximately
44 feet between curbs. The approach roadway
on each side has one lane in each direction with
a 4-foot shoulder and a 12-foot-wide raised
planted median protected by concrete curbing.
The raised median terminates immediately prior
to the bridge and is replaced by a painted
median over the stmcture. Since the roadway
width at the bridge is less than 60 feet wide,
approach railing is required at each end of the Carlsbad Boulevard Overhead, looking north

bridge for both directions, per the Caltrans Traffic Manual Section 7-03.4 "Guardrail at Fixed
Objects." A design exception will be required to eliminate the guardrail if desired by the City.
The Encina Discharge Channel is located on Carlsbad Boulevard and has a roadway width of 96
feet. This cross section consists of a 12-foot raised median, a 30-foot northbound travel-way and
shoulder, a 40-foot southbound travel-way and shoulder, an 8.5-foot sidewalk on the west, and a
5.5-foot sidewalk on the east. Since the roadway width is greater than 60 feet, approach railing
is only required to the right of approaching traffic per Caltrans Traffic Manual Section 7-03.4
"Guardrail at Fixed Objects."
The length of guardrail protecting a fixed object shall typically
have a minimum length of 50 feet preceding the object,
exclusive of an approved end treatment. Longer lengths of
guardrail may be needed on embankments where, in effect, the
approach guardrail becomes an embankment guardrail. This
occurs at Carlsbad Boulevard Overhead where the roadway is
elevated over the railroad tracks, creating embankment slopes
on the approach, specifically on the southeast, southwest, and
northwest corners. The northeast comer currently has a
retaining wall with decorative railing on top. A design
exception for approach railing may be investigated for the
northeast comer.
Carlsbad Boulevard Overhead, northbound approach
The Encina Discharge Channel stmcture will only require approach railing to the right of traffic.
The west side of the stmcture will require installation of the approach railing but must not block
a gated access point at the north end of the fence. The east side will be more difficult due to the
location of the property line, and may require extending either the concrete barrier or approach
railing to the entrance to the Encina Power Station. Due to the location of the Encina Discharge
Channel, Coastal Commission approval will be required.
CONCRETE BARRIER RAILING
Carlsbad Boulevard Overhead
The posted speed for Carlsbad Boulevard at this location is 35 mph. The design speed for a two-
lane arterial with unlimited access and extensive development is between 30 and 40 mph per
Caltrans Highway Design Manual Table 101.2. The replacement concrete barrier rail must
satisfy the design requirements for a design speed of 40 mph maximum. Based on the FHWA
Caltrans Bridge Rail Guide 2005, the replacement railing must satisfy Test Level 2 (TL-2) which
is an 820-kg (1808-lb) car and a 2000-kg (4,408-lb) tmck striking the barrier at 70 kph or 45
mph.
The original railing on the bridge is an open style railing that has suffered from vehicle collisions
and deterioration over the years. Researching the FHWA Caltrans Bridge Rail Guide 2005, the
following barriers will satisfy the strength requirement and also provide an open appearance.

Page 3
Caltrans Type 80:
This railing provides an open appearance while
meeting all of the strength requirements for impact.
The railing also has a sidewalk option (not shown).
The standard railing is not designed for the installation
of chain-link fencing on top, and would require
modification if chain-link fencing is required.
Texas C411:
This railing provides an open appearance similar to the
existing railing while meeting all of the strength
requirements for impact. This railing may be used with or
without a sidewalk. The standard railing is not designed
for the installation of chain-link fencing on top and would
require modification if chain-link fencing is required.
Texas T411:
This railing provides an open appearance similar
to the existing railing while meeting all of the
strength requirements for impact. This railing is
similar to the C411 but is only designed for use
without sidewalks. The standard railing is not
designed for the installation of chain-link fencing
on top and would require modification if chain-
link fencing is required.
Carlsbad Boulevard Overhead crosses two rail lines owned by NCTD. Simon Wong
Engineering was unable to contact NCTD regarding requirements for bridge railing of stmctures
that cross their tracks. During the design phase coordination with NCTD will be required to
determine if a chain-link railing is required.
Solid concrete barrier rail designed to accommodate the installation of a chain-link fencing on
top is shown below. Modifications to these barriers to enhance the architectural appearance are
available and include staining the concrete, utilizing form liners to simulate rock on the exterior
face, and architectural details to the entire barrier itself Examples of some of these barriers are
shown below.

Caltrans Type 732:
This is a standard Caltrans railing with a solid face
and is intended for conditions without a sidewalk
option. This railing would meet all of the strength
requirements necessary. Architectural enhancements
of the railing are possible through application of a
stain or architectural treatment to the exterior
portions. This railing allows for chain-link fencing to
be installed on top and could be used on the north
side of the stmcture where no sidewalk is present.
Caltrans Tvpe 26 (Mod):
This is a modification of a standard Caltrans Type
26 Barrier. This barrier incorporates architectural
enhancements to the vertical concrete parapet.
Matching architectural features to the non-
sidewalk (north) side would result in unacceptable
protmsions on the surface. This railing allows
for chain-link fencing to be installed on top. A
modified Type 26 barrier could be used on the
south side of the stmcture.
BARRIER INSTALLATION
Removal of the existing barrier located on Carlsbad Boulevard Overhead will require traffic
control on Carlsbad Boulevard and flagging on the railroad tracks. The removal of the railing on
the north side of the stmcture will consist of demolition of the barrier itself Demolition of the
railing on the south side of the stmcture will require removal of the railing and sidewalk.
Challenges exist in the removal and replacement of the
sidewalk and barrier on both the south and north sides
of the stmcture. As shown in the photo (right), the
south side has a sidewalk that spans across support
elements that are cast integrally with the exterior girder.
Special care will be required during the demolition to
prevent debris from falling onto the track below and
will require traffic control to provide pedestrian access
during construction. Temporary falsework or
formwork will be required during the replacement of
the sidewalk and barrier. On the north side, the
removal and replacement can be completed from the
bridge deck but would still require traffic control and
flagging for work over the rail lines.

The condition of the existing concrete deck should be investigated during the preliminary design.
Previous work on this bridge identified potential "soft spots" in the deck. The deck is currently
covered with an asphalt concrete overlay; however, this should be removed in key sections to
sound and test the concrete to verify strength. Tj^ical barrier rail installation utilizing drilling
and bonding of reinforcement into the bridge deck is expected on the north side replacement,
with the assumption that "soft spots" are not encountered.
The existing barrier located on the north side of the bridge is 1 foot, 8 inches wide. An
architecturally enhanced rail such as the C411 is 1 foot, 2 inches wide and will fit within the
limits of the existing railing. A Standard Type 25 railing is 1 foot, 9 inches wide and will
encroach into the shoulder by 1 inch.
ENCINA DISCHARGE CHANNEL
The posted speed for Carlsbad Boulevard at the Encina Discharge Channel stmcture is 35 mph,
while the design speed for an urban arterial with unlimited access and extensive development is
between 30 and 40 mph per Caltrans Highway Design Manual Table 101.2. The proposed
concrete barrier rail must satisfy the design requirements for a design speed of 40 mph
maximum. Based on the FHWA Caltrans Bridge Rail Guide 2005, the replacement railing must
satisfy Test Level 2 (TL-2) which is an 820-kg (1808-lb) car and a 2000-kg (4,408-lb) tmck
striking the barrier at 70 kph or 45 mph.
Currently only a chain-link fence is in place on each side of the culvert. This chain-link fence
will be removed and replaced with a concrete barrier with a TL-2 rating or above and with a
chain-link fence on top.
Adjacent to the Encina Discharge Channel is an
architecturally enhanced sea wall installed by the Army
Corps of Engineers in 1992. In order to maintain the
aesthetic characteristics of the corridor, a modified Type
26 concrete barrier similar in appearance to the sea wall
may be used. This type of concrete barrier is able to
accommodate the installation of chain-link fence on top,
which would be required in order to maintain access
control.
Existing Carlsbad Boulevard Sea Wall
Due to degradation of the west edge of the culvert,
removal and replacement of a portion of the exterior deck
may be necessary prior to the installation of a barrier.
During the design phase of the project a detailed
investigation of these exterior portions of the culvert
should be performed and should include mechanical
sounding of the concrete to determine the extent of the
Encina Discharge Channel, west side

removal. As part of the barrier rail replacement plan, removal limits of the unsound concrete and
a repair plan should be shown.
BARRIER INSTALLATION
The Encina Power Station falls under the jurisdiction of Homeland Security and has special
security requirements including maintaining an access control fence around the property at all
times. Installation of a concrete barrier on the east side of the culvert will be a challenge and is ^
likely to require closure of the east sidewalk in order to provide adequate room to work. ,^
The west side of the channel may require partial or full closure of the sidewalk as well, to cjQt^^ y
provide adequate room to work, depending upon the extent of the repairs required to the edge of
the channel.
The width of the culvert per the as-built plans is 100 feet, 4.5 inches. Based on the as-built plans
for the roadway, median and sidewalks the required width of Carlsbad Boulevard is 96.0 feet.
Currently on the east side of Carlsbad Boulevard at the culvert the sidewalk is 5.0 feet wide and
stops short of the edge of the culvert by approximately 14 inches where there is an existing
chain-link fence. This 14 inches will allow for the installation of a concrete barrier similar to a
Type 26 concrete barrier and not reduce the width of the sidewalk. On the west side of Carlsbad
Boulevard the sidewalk is 11 feet, 10 inches from the edge of the culvert to the nose of the curb.
The sidewalk is supposed to be 8 feet, 6 inches in this area per the as-built plans leaving 3 feet, 4
inches for the barrier rail installation.
The barrier railing on each side is anticipated to be installed utilizing standard drilling and
bonding of the barrier reinforcement into the culvert, however, rehabilitation of the edge of the
culvert may be required prior to the installation of the concrete barriers.
