    CONNECTING THE LOOP THREE RIVERS PARK Defining Strategies for Implementation Presented by the Riverlife Task Force Pittsburgh May 2003 CONNECTING THE LOOP THREE RIVERS PARK Defining Strategies for Implementation n August 2002, Mayor Tom Murphy issued a challenge to the Riverlife Task TABLE OF CONTENTS Force: How can we link Pittsburgh’s three rivers with a continuous system of BACKGROUND 3 trails and riverfront parkland for people of all ages? Which trails are currently ELEMENTS OF THE LOOP 4 TRAIL SEGMENT ANALYSIS 7 connected? Which are not? How do we establish connections that do not yet APPENDIX 87 exist? What exciting destinations can we create along the shoreline? I. PROJECT SUMMARY 88 I II. ANTICIPATED PROBABLE COSTS 94 After walking the entire shoreline within the bounds of Three Rivers Park, we hired III. EXCERPTS FROM RIVERLIFE 96 a team of architects, landscape architects and civil engineers to present options DESIGN GUIDELINES and propose solutions for riverfront trails, bridge connections and water landings. Connecting the Loop presents a range of ways to establish a continuous trail system with acquisition, design and construction that can be phased over the next decade. We offer this as a resource for property owners, planners, developers, public agencies and non-profit organizations, and we urge them to seize moments of opportunity to undertake projects, large and small. For the Riverlife Task Force, the plan will also serve as a guide as we work with public and private stakeholders to develop long and short-term priorities. We are proud to present Connecting the Loop and we invite you to work with us to return Pittsburgh’s greatest asset to the public — its rivers and miles of shoreline.

U.S.DOT BUILD Grant: Butler County - State Route 228 Improvements The U.S. Department of Transportation has recently awarded $25 million of discretionary BUILD grant funding to Butler County to construct roadway, intersection, and pedestrian improvements along two segments of State Route 228 and State Route 3020 (Freedom Road). The region’s TIP and Long Range Plan need to be amended, and the region’s air quality conformity assessment needs to be updated before the project can begin construction. SPC is seeking public feedback as part of the amendment process. The project includes improvements on Freedom Road from Powell Road to Haine School Road, and on State Route 228 at the intersection with Three Degree Road. Various improvements include adding new travel lanes, widening existing lanes, adding turn lanes, converting intersections to roundabouts or jug handles, installing ADA ramps, adding multi-use paths and sidewalks, upgrading traffic signals, and adding pavement markings.

It is also rich in history. The county’s many historic farms, villages, and winding country roads contribute to a strong “sense of place” that appeals to residents and visitors alike. The people who have called Somerset County home for thousands of years have created a unique cultural environment unlike any other. From the ancient settlements in the “Turkeyfoot” region of the south, to the rolling farm country of Brothers Valley in the center, to the coal patch towns of the north, history is everywhere in Somerset County. Something interesting always seems to lie just around the next bend in the road. The county’s development was shaped by its hydrology and rugged topography. Although its forested hills hid immeasurable mineral wealth just below the surface they also limited the areas suitable for settlement and agriculture.

Concrete Slab and Arch Bridges 101 Masonry Bridges Heritage Study of Masonry Bridges in NSW 2005 1 Historical Overview of Bridge Types in NSW: Extract from the Study of Masonry Bridges in NSW HISTORICAL BACKGROUND TO MASONRY BRIDGES IN NSW 1.1 History of early bridges constructed in NSW Bridges constructed prior to the 1830s were relatively simple forms. The majority of these were timber structures, with the occasional use of stone piers. The first bridge constructed in NSW was built in 1788. The bridge was a simple timber bridge constructed over the Tank Stream, near what is today the intersection of George and Bridge Streets in the Central Business District of Sydney. Soon after it was washed away and needed to be replaced. The first "permanent" bridge in NSW was this bridge's successor. This was a masonry and timber arch bridge with a span of 24 feet erected in 1803 (Figure 1.1). However this was not a triumph of colonial bridge engineering, as it collapsed after only three years' service. It took a further five years for the bridge to be rebuilt in an improved form. The contractor who undertook this work received payment of 660 gallons of spirits, this being an alternative currency in the Colony at the time (Main Roads, 1950: 37) Figure 1.1 “View of Sydney from The Rocks, 1803”, by John Lancashire (Dixson Galleries, SLNSW).
