VI. DESIGN ELEMENTS
A. Geometrics
1. Vertical Geometry
The vertical geometry on Route U.S. 130 will be raised to meet the elevation of the proposed fixed span bridge over Raccoon Creek. The grade rate north and south of the Creek is -2.975% and 2.72% respectively.
2. Horizontal Geometry
The horizontal alignment will be shifted to the west in order to maintain traffic along Route U.S.
130 during construction and minimize the residential right of way impacts.
3. Highway Sections
The cross section on Route U.S. 130 will include two 12 foot lanes in each direction of travel with minimum 8 foot outside shoulders and 3 foot inside shoulders separated by either a concrete median barrier or guide rail. The typical section will vary in the vicinity of the acceleration and deceleration lanes proposed along Route U.S. 130 for Route U.S. 322 interchange.
B. Pavement Engineering

Mill up to 1” depth and pave with 3” Hot Mix Asphalt 12.5M76 Surface Course
Secondary Roads
Mill up to 2” depth and Pave with 2” Hot Mix Asphalt 12.5M64 Surface Course.
Note- At both ends of the approach of Route U.S. 130, break the existing pavement to accommodate new pavement.
Incidental Recommendations
The areas exhibiting moderate to severe fatigue cracking, patching, and potholes should be repaired in accordance with division 400 & 450 of the 2007 Standard Specifications book. Include the standard item “Hot Mix Asphalt Pavement Repair and Concrete Pavement Repair prior to overlay.”
Saw cutting of existing pavement prior to excavation and sealing of joints must be done between the new and existing pavement section to remain.
Excavate and replace any unstable material with Subbase which is Subbase I-3.
C. Geotechnical Design
A geotechnical investigation was limited to a review of New Jersey Department of Transportation pavement data tested in September 2004. The following table provides a summary of this data:

Based on the above ratings, an analysis was performed on the deficient pavement based on the criteria listed below:
Rough Only: Road segments with excessive roughness (IRI > 170) but without severe distress (SDI > 2.5).
Distressed Only: Road segments with severe distress (SDI 2.5) but without excessive roughness (IRI 170).
Rough and Distressed: Road segments with excessive roughness (IRI > 170) and severe distress (SDI 2.5).
Subsurface exploration program and geotechnical engineering evaluation have been performed in connection with the replacement of the U.S. Route 130 Bridge over Raccoon Creek.
The subsurface conditions encountered north of Raccoon Creek consisted of granular soils composed predominantly of coarse to fine sand intermixed with varying amounts of silt and gravel. The subsurface conditions encountered on the south side of Raccoon Creek consisted of granular soils underlain by marine tidal marsh deposits and geologically older marine granular soils.
Deep foundation elements consisting of driven closed-end concrete filled pipe piles are recommended to support the abutments and three piers of the reconstruction of the U.S. Route 130 Bridge over Raccoon Creek. Due to the presence of soft compressible soils at the south approach embankment, it is recommended that column-supported embankment be utilized such that the applied embankment and vehicular loads are transferred directly to the underlying dense granular soils. The construction of approach embankments will requires that retaining walls be installed and mechanically stabilized earth (MSE) wall system such as manufactured by Reinforced Earth is recommended for the use in this project.
Please refer to the Subsurface Exploration & Geotechnical Engineering Evaluation Report dated August 2010 for more detailed information.
D. Survey Parameters
The base mapping for this project was developed through a combination of aerial photogrammetry and conventional surveying methods. The aerial photogrammetry work was performed by BAE Systems ADR, 124 Gather Drive, Suite 100, Mt. Laurel, NJ 08054. The primary GPS horizontal and vertical control survey data was provided by the N.J.D.O.T. Geodetic Survey Unit.
The aerial photogrammetric portion consists of two segments, one high level flight, stations: HV 1 to HV 10, for mapping of adjacent wetlands and environmentally sensitive areas, southwest of the existing vertical lift bridge and one low level flight, stations HV 11 to HV 47 for mapping of existing road surface and surrounding topography.
Two primary GPS control stations were established and utilized as base-stations in preparation for performing Real-Time Kinematic (RTK) GPS surveying on forty seven (47) photo control stations.
Observations for the primary survey control were performed on one day, November 16, 2007 (Julian day 320). Two 60-minute sessions were observed. Observations for the photogrammetric survey control were performed on two days: November 28, 2007 (Julian day 332) and January 23, 2008 (Julian day 023).

A First-Order GPS Control Survey providing Horizontal and Vertical control was supplied by NJDOT, Division of Design Services, Bureau of Civil Engineering Geodetic Survey Unit.
A loop bench run was performed utilizing a Leica NA 2002 Digital Level, Mfr. Serial No. 309990, N.J.D.O.T. No. 107436, serviced and calibrated on 02/13/08.
Additional Cross Sections and Topography were provided in areas which could not be obtained through Photogrammetry. Directions and distances were observed utilizing two Leica TRC 1103 Electronic Total Stations, Mfr. Serial No. 619623, and 619621, N.J.D.O.T. No. 107419, and 107418, serviced and calibrated on 07/13/09.
NJDOT Control Monuments and existing property corners were uncovered and located for the purpose of associating the Route U.S. Existing Baseline with the newly obtain Photogrammetric Survey.

General Notes
A formal traverse was not conducted due to the fact that all horizontal control was established thru a “First-Order GPS Control Survey”.
Only 2 N.J.D.O.T. monuments and 6 property corners were found throughout the project, therefore Panel Points, inlets, guide rail, ends of curb, and the Bridge Deck were used to tie down the Existing Route U.S. Baselines.
E. Traffic Engineering
McCormick Taylor collected manual traffic turning counts in February 2004 at the intersections of Route U.S. 130 with Island Road and Main Street. Classifications of medium and heavy trucks were also collected as part of this count effort. A growth rate of 2.00% was applied to the 2004 base year volumes to obtain 2006 and 2026 design year volumes. Level of Service (LOS) analyses conducted for this highway was performed using the HCS+ 5.21 version of the Highway Capacity Software (HCS) which utilizes the methodology contained in the Highway Capacity Manual. The levels of service for the base year 2006 and design year 2026 have been provided in the Table below.

Traffic Signals
There are no proposed traffic signals for the project.
2. Signing
All signing applications are derived from the Manual on Uniform Traffic Control Devices. One overhead sign structure will be upgraded.
3. Striping
All striping applications are standard and derived from the Manual on Uniform Traffic Control Services. Standard striping applications include centerlines, lane lines, and edgelines.
4. Traffic Control/Staging
Construction will be staged to create a minimum amount of disturbance to existing traffic patterns
No detours are planned for this project.
A reduction to the speed limit is recommended within the project limits.
There will be a need to reduce the number of lanes to one in each direction of travel on Route U.S. 130 during construction.
5. Maintenance of Traffic:
Stage 1
Stage IA
Tasks to be completed include the following:
Set up all traffic control devices and warning signs as shown in the lanes.
Mill 6 inch and pave 6 inch the NB shoulder area for traffic staging.
In the north end of the project remove the portion of the median guide rail and install temporary pavement to provide an opening for traffic to cross from southbound travel lanes to northbound left temporary lanes for stage 1B construction.
In the south end of the project remove the portion of guide rail and build permanent pavement to cross SB traffic on NB left lanes back to the SB side. Install temporary telescoping guide rail end terminal to protect the existing median guide rail.
Cover / remove / replace the OH sign structure at NB station 58+80 for the new traffic pattern. Restrict Route U.S. 30 northbound traffic to one lane and re-stripe and install construction barrier curb on Route U.S. 130 northbound. Place barrier curb to stop access from Sheets Avenue to Route U.S. 130 northbound.
Place detour signs to close Island Road during stage II and stage III construction.
Relocate the gas main along the south bound side of Route U.S. 130.
Stage IB
Shift the SB traffic into the NB left lanes using improvements from stage IA. The Route U.S. 130 lane configuration for this stage will be one lane in each direction.
Construct a portion (±32 ft width section) of the realigned southbound Route U.S. 130 Bridge and approaches. Construct the median barrier on the south side of the bridge.
Install temporary sheeting in the median and permanent southbound retaining wall to build the road box. Complete all the drainage, retention basins and all roadwork.
Pave the road up to the intermediate course then install temporary construction barrier next to the temporary sheeting.
Construct the required crossing for Route U.S. 130 NB traffic to shift to the newly constructed portion of the bridge.
Stage 2
Tasks to be completed include the following:
Shift Route U.S. 130 traffic pattern to the newly constructed southbound section. Access to Route U.S. 130 northbound to Route 322 eastbound ramps will be maintained.
Demolish the existing structure, and remove all the piles. Demolish the bridge house and remove all machinery.
Continue the work on the northbound Route U.S. 130 Bridge and approaches, road box and North bound retaining wall.
Remove temporary sheeting in the median then construct the median barrier curbs and the permanent northbound retaining wall. Complete all the drainage and all roadwork on Route U.S. 130.
Construct the road adjacent to Route U.S. 130 northbound and the emergency access road to Route U.S. 130 northbound. Complete the construction of Main Street and Island Road connection and reopen Island Road access to Main Street. Install all permanent guide rails.
Stage 3
Tasks to be completed include the following:
Shift the traffic back to the outer lanes of the constructed realignment to allow for median construction. Construct the median / barrier curb on the north side of the project.
Access to Route U.S. 322 eastbound to Route U.S. 130 southbound and the Route U.S. 130 northbound to Route U.S. 322 eastbound will be maintained during Stage III.
During nighttime/weekend/ off peak hours, pave the surface course, construct permanent traffic striping / markings and all remaining works required for the project.
