Marshalls Creek Bypass, Monroe County, PA
(Client: PennDOT District 4-0)
|
 |
This project is relocating US Route 209 from the center of the Village of Marshalls Creek in an effort to reduce traffic congestion and improve safety and access throughout the corridor. US 209 will be relocated to the east of the village with a new two lane, limited access roadway approximately 2.5 kilometers in length. Work has entailed a new 2 mile bypass including one new roundabout intersection and one new signalized intersection. The project has completely restructured existing signalized intersections in the Village. The new bypass and resulting new traffic patterns required new ATR and manutal turning, movement counts to confirm projected traffic volumes and optimized signal timing plans for actual traffic volumes, as well as Synchro and Sim Traffic analysis, manual signal optimization and oversight of system construction, commissioning, and optimization. |

S.R. 3046, Section 301 South Valley Parkway, Luzerne County, PA
(Client: PennDOT District 4-0) |
 |
This $34.5 million project has entailed project management, preliminary engineering and final design and environmental permitting for 4 miles of new roadway to connect Luzerne County Community College and the Hanover Township business district with State Route 29. The project was originally scoped to be a four-lane freeway with two interchange access points at a cost of $110 million. Though the needs assessments, public involvement, alternate studies and the VEACTT process, it was scaled down to a two lane facility with one interchange at a reduced construction cost of $34.5 million. The Borton-Lawson team evaluated numerous traffic calming strategies for residential areas through which this parkway runs. These included curb extensions, traffic circles/roundabouts, speed humps and tables, raised crosswalks, semi-diverters, diagonal diverters, street closures/cul-de-sacs, one-way streets, multi-way stop sign installation, speed limit signing, etc.

| I-81 Lackawanna River Bridge, Lackawanna County, PA |
 |
| This $20 million project's primary objectives were to rehabilitate the expressway and increase motorist safety through bridge rehabilitation, mainline widening and ramp design enhancements. The I-81 corridor is the primary north-south highway in the Wilkes-Barre and Scranton area, serving a heavy mix of both regional and commuter traffic. Over 53,000 vehicles per day use this stretch of highway near Exit 190 – which made for periods of oversaturation, reduced travel speeds and driver frustration. Our tasks included the development of the traffic control plan, H&H studies for the replacement of the I81 bridge over Lackawanna River, design of the Main Street Bridge rehabilitation, removal of a bridge over an abandoned railroad, and the conversion of the SR 2017 bridge to a pedestrian structure. Also included was temporary signal retiming and associated plans at eight signalized intersections to accommodate detoured traffic. |

| Scranton Signal Upgrade and Streetscape Improvements, Scranton, PA |
| This $1 million project, part of a work order under an Open-End contract with PennDOT, District 4-0, included the design of upgrades to 3 signalized intersections and the design of streetscape beautification improvements which were coordinated with a neighborhood business association and property owners. Streetscape improvements included planters, benches, new sidewalks, street lighting and curbing in the Market Street business area. Traffic design work included manual turning movement counts and automatic 24-hour counts, analysis of crash data, signal warrants, capacity analysis, and signal timing and signal phasing using Transyt 7-F. Roadway design included line striping for lane revisions and pedestrian movements. |

NB-716 Bridge Replacement and I-3R Mainline Reconstruction and Safety Feature Upgrade Project, Lackawanna and Luzerne Counties, PA
(Client: Pennsylvania Turnpike Commission) |
 |
| This project consisted initially of preliminary engineering for a bridge replacement carrying State Route 3022 over the Northeast Extension of the Turnpike. The project scope expanded to include 15 miles of roadway work including 5 miles of pavement replacement, shoulder and drainage reconstruction; 10 miles of median barrier installation; and 15 miles of guide rail end treatment and bridge barrier upgrades. Engineering tasks included traffic control plans, right-of-way plans, field surveys, existing curvilinear plan development, roadway plans, utility coordination/ relocations, structure plans, geotechnical investigations, erosion and sedimentation control plans, and NPDES Permitting for the Turnpike Mainline and re-aligned a portion of State Route 3002. |

| Great Wolf Lodge, Scotrun, PA |
 |
| This $70 million project included all aspects of land development and site engineering for the 95-acre site. Borton-Lawson's scope of services included all boundary and topographic survey, traffic impact studies, site design including stormwater management, 620 parking spaces, lighting and landscape plans, highway access design and associated permits, on-site water system evaluation and design of and permitting of a 90,000 gallon per day sewage treatment plant. Traffic engineering tasks included performing a Traffic Impact Study at an exit of I-80 that had been experiencing congestion and safety issues for many years. The resultant recommendations solved many of the existing roadway issues to ensure a safe access for the Lodge and for existing residents and visitors. A traffic signal was designed at the intersection of Route 611 and the Interstate 80 Exit 298 off ramp. In addition, the base of the ramp was widened to accommodate additional storage. The volume density controller ensures that the signal will operate in the most efficient manner possible, by allocating green time based on actual vehicle demand. To prevent ramp traffic from backing up toward the interstate, a queue detection loop was installed on the ramp. |

| Mohegan Sun at Pocono Downs SR 315 & SR 115 Traffic Impact Mitigation Design, Wilkes-Barre, PA |
 |
| This $750,000 project consisted of the implementation of intersection improvements at the SR 309, Exit 1 ramp/SR 315 intersections, and the PA Turnpike Exit 105 ramp/SR 115 intersection in Luzerne County, PA. The improvements were part of the work identified in a Traffic Impact Study for the Mohegan Sun at Pocono Downs casino project. Work included signal upgrades, additional turn lanes, and related drainage improvements at the SR 309 intersection. The SR 115 intersection required the design and installation of a new signal with minor lane reconfiguration. Our scope included the preparation of HOP plans and bid documents, obtaining E&S permits and administering the construction contracts. |
