The October 2014 newsletter is now available for download.

Based on the popularity of our previous two Blue Jackets outings, we, in conjunction with ASHE and Engineers Club of Columbus, have a group package of 50 tickets to the Blue Jackets-Hurricanes game. Tickets are $10 per member and $15 per guests. We're accepting pre-payment using PayPal. As these tickets usually sell for $50 face value, it's a great deal. Prior to the game, we’ll have a social put on by the Younger Members group at Brother's, so even if you don't want to go to the hockey game, please come out for drinks, food, and fellowship.

Topic: Scioto Greenways - A Riverfront Transformation

(Online registration and payment available, see bottom of page.)

The Scioto Riverfront in Downtown Columbus has been transformed as a result of hundreds of millions of dollars in public and private developments in the RiverSouth area. But while substantial public and private investments along the Scioto River have created world-class amenities, the river has remained a slow-moving, overly wide pool of sediment-laden water due to the presence of low head dams.

The removal of the Main Street Dam begins to restore the natural course of the river, improve the ecological systems and river habitat, provide new recreation options, and provide an opportunity to further leverage existing investments by creating a stunning 33-acre greenway through Downtown Columbus, Ohio.

We will be discussing some upcoming events and other things we have planned for the year. Come out and have some free food and drinks!

*Open only to Central Ohio Section Members

Purpose and Background
Recent advances in bicycle facility design guidance have led to increased demand from government agencies and the public to implement many of these innovative treatments. As more of these facilities are being implemented, users are recognizing the host of safety benefits and greater comfort level generated from the increased separation from automobile traffic and enhanced intersection treatments. Agencies throughout the country are using the design guidance recently issued within the National Association of City Transportation Officials Urban Bikeway Design Manual, in association with the guidance set forth in the established U.S. manuals such as the AASHTO Guide for the Development of Bicycle Facilities and MUTCD, to implement these facilities. The primary goals of this webinar are to familiarize transportation engineers/planners with the newest innovations in the bicycle facility design practice. The webinar will discuss recent developments in available design guidance and considerations when designing these facilities.

Topic: Electrical Engineering Basics for Civil Engineers

You are invited to a Technical Presentation and Meeting of the Lower Scioto Valley Chapter of ASCE. The Chapter is part of the Central Ohio Section of ASCE.

The presentation will include electrical engineering basics, and some guidelines for Civil Engineers when working with Electrical Engineers on multi-discipline projects.

Topic: Roberts Road Diverging Diamond Interchange (DDI)

(Online registration and payment available, see bottom of page.)

A congested interchange in the midst of a heavily traveled industrial, commercial, and residential area has received a major overhaul. The previous diamond interchange at I-270 & Roberts Road in Columbus, Ohio has been transformed into a Diverging Diamond Interchange (DDI) – an emerging and cost effective roadway solution designed to improve safety, reduce crashes, and ease congestion. It is the first DDI constructed in the state of Ohio and was the 23rd in the United States.

The previous diamond interchange had geometric design deficiencies and a high frequency of congestion-related crashes. The former interchange also couldn’t handle the high volume of traffic that travels through it – including a large amount of trucks that drive area commerce.

Some key components of the I-270/Roberts Road DDI include:

• No right-of-way acquisition
• No environmental impacts
• Dedicated bike lanes through the interchange – first in the U.S.
• Dual turn lanes for large trucks
• Design of DDI merged with a maintenance design project for the overhead bridges that was already underway
• Extensive public involvement and education process
• Full closure of the bridges through the interchange; four-month construction schedule
• $10.6M construction cost

This presentation will discuss the intricacies of the planning effort, the key aspects of the design, and lessons learned during both design and construction. As the Project Manager of the design team, Mr. Toombs will provide insight about design and construction, including lessons learned during various points in the process.

More than 250 experts from 30 states and 19 state departments of transportation attended the first two International Conferences on Perpetual Pavement (ICPP), held in 2006 and 2009, to discuss optimal design and construction approaches for asphalt pavements designed and built to last longer than 50 years without requiring major structural rehabilitation or reconstruction, and needing only periodic surface renewal in response to distresses confined to the top of the pavement.
