      <title>Fast-track schedule drives design</title>
      <link>https://trid.trb.org/View/1304912</link>
      <description><![CDATA[A project to widen and reconstruct nearly 1.5 miles of roadway in Johnston, Iowa was announced in early 2010. The design included four multilane roundabouts to help address difficult traffic conditions along the corridor. They were designed to improve traffic flow and pedestrian safety, as well as to reduce delays. The project was designed and delivered on a fast-track schedule. The software used helped streamline the design process and automated repetitive tasks. The project was completed In November 2012. Studies have shown that the roundabouts will likely reduce traffic fatalities, injuries, and crashes. They are also predicted to save travel time and fuel consumption.]]></description>

      <title>Rail revival challenge</title>
      <link>https://trid.trb.org/View/1304910</link>
      <description><![CDATA[Class one railroads in the United States are currently experiencing a revival of growth. Train technology has improved to become more energy-efficient, and train use has grown in terms of both passengers and freight, with growth expected to continue. It is necessary to maintain rail infrastructure to keep up with the growth the industry is experiencing. The demand for trains is greater than the capacity of the rail lines, which causes delays. It is necessary for many railroads to build additional tracks. Recently, a second track was added to the Los Angeles-to-San Diego line in Carlsbad, California. The project improved the capacity and reliability of passenger train service. There are similar projects being developed around the United States. Adding additional tracks has been shown to be a highly successful solution to capacity problems.]]></description>

      <title>Urban Infrastructure Challenge</title>
      <link>https://trid.trb.org/View/1304911</link>
      <description><![CDATA[Reliable infrastructure is necessary for cities to function and thrive. Today, 76 percent of the United States population lives in cities, and that percentage is expected to grow. At present, the amount of investment going into infrastructure is not enough to ensure its reliability. It is necessary to improve the planning and design methods of urban areas to support sustainable infrastructure, in order to improve cities not just for the present, but also for the future. Planning, design, and delivery need to be rethought, and processes and technology must be modernized. Recent technology, including three-dimensional modeling, can aid the process in order to move forward with the development of cities.]]></description>

      <title>Defeating disaster</title>
      <link>https://trid.trb.org/View/1301689</link>
      <description><![CDATA[Disasters, such as storms and flooding, can wreak havoc on communities and property. There are many strategies in planning, design, and infrastructure that can help engineer cities to be more resilient. Resilience engineering helps to protect communities in advance of a disaster, minimizing damage and improving safety. Engineers typically base designs on historical weather data, but recent years have seen an increase in non-typical weather trends. Strategies for resilience engineering include locating key infrastructure as far from floodplains as possible, keeping emergency protocols accurate and up-to-date, and improving building codes and zoning ordinances. It is necessary to continually evaluate strategies in order to be able to adapt.]]></description>

      <title>Rebuilding Detroit: From the ground up</title>
      <link>https://trid.trb.org/View/1301691</link>
      <description><![CDATA[Despite its state of bankruptcy, the city of Detroit, Michigan is currently experiencing growth. There has been a great deal of commercial, industrial, and residential developments over the last few years, and in 2013, a number of new businesses opened in the Midtown district. Investments and the growth of business, however, need a strong infrastructure system of streets and utilities. This has required significant civil engineering work to improve infrastructure, some of which has been in use for over a century. Detroit’s Department of Public Works has developed a plan for non-motorized transportation, which will improve surface streets and encourage walking and cycling.]]></description>

      <title>Road to redevelopment</title>
      <link>https://trid.trb.org/View/1301693</link>
      <description><![CDATA[The Bill Delahunt Parkway opened in August, 2013 at the site of a former naval air base in Weymouth, Massachusetts. The parkway is allowing local development agencies to redevelop the former base by improving mobility for pedestrians and motorists with roads, bridges, and sidewalks. The parkway improves infrastructure and economic development opportunities for local residents. The project was developed under a  design-build contract and involved design for roadways, stormwater management, traffic, and bridges, as well as paths for cyclists and pedestrians. Communication was important for the project, which had a tight schedule and limited finances. Multiple stakeholders cooperated to make the project a success.]]></description>

      <title>Parking planning</title>
      <link>https://trid.trb.org/View/1301690</link>
      <description><![CDATA[As part of smart growth developments where walking and public transit are given attention as well as automobile use, planners need to rethink the role of parking in city centers and urban areas. Communities often must compete for downtown shoppers and businesses with suburban malls and office parks that offer large amounts of free parking. Many cities have attempted to compensate with minimum parking requirements for new developments and lowered rates for on-street parking. However, these measures have caused policies to continue encouraging driving over other modes of transport. It is important for cities instead to develop infrastructure and programs to encourage walking and more environmentally friendly modes of transportation.]]></description>

      <title>When a work bridge won’t work</title>
      <link>https://trid.trb.org/View/1301692</link>
      <description><![CDATA[Two Interstate 84 Sandy River bridges near Portland, Oregon needed replacement but were at risk of flooding. The Oregon Department of Transportation (ODOT) began looking for ways to reduce the effects of high water levels in the surrounding area. For other bridge projects, ODOT had been able to build detour and work bridges next to the existing bridge, but the Sandy River terrain made this project more complicated. The area is prone to flooding and winter storms, so work and detour bridges required steel piles for support. The work bridges could be partially removed during the heavy storm season, which helped ease high water levels.]]></description>

      <title>A sign of the times</title>
      <link>https://trid.trb.org/View/1301694</link>
      <description><![CDATA[The Olmstead Parkways in Louisville, Kentucky were designed in the 1890s and today are listed on the National Register of Historic Places. Over the years, the parkways evolved as transportation became more automobile-centric. By the end of the 20th century, the Olmstead Parkways featured busy four-lane roads with traffic arteries, reflecting the growth of automobiles and the local area. Today, renovations are being planned that reflect the current shift in the transportation industry, with an increased emphasis on public transit, pedestrians, and cyclists. Designers plan to create a more park-like space, with facilities for walkers, joggers, and cyclists, and they have sought advice from the public to determine how best to meet their needs.]]></description>

      <title>Tunneling trends</title>
      <link>https://trid.trb.org/View/1280909</link>
      <description><![CDATA[There has been an increase in tunnel projects in the United States in recent years. Civil engineers have been involved in expanding the boundaries of tunnel design and construction, and transportation and water tunnels across the country are setting records and developing new technologies and design. In the last decade, the technology of Tunnel Boring Machines has progressed, making underground construction more sophisticated and leading to an increase in development of underground systems. Design of tunnel liners and waterproofing has improved, and an increase in automation has allowed tunnel construction to be performed faster, cheaper, and safer. In the near future, it is likely that tunneling for transportation projects will increase.]]></description>

      <title>Safe in Seattle</title>
      <link>https://trid.trb.org/View/1280912</link>
      <description><![CDATA[A new tunnel on the State Route 99 in Seattle will break the record for diameter, featuring two two-lane freeways, one on top of the other. The tunnel is so big that a new tunnel boring machine had to be built for it. A system of sensors has been installed to monitor construction in the event of a tunnel collapse. A team will remain onsite throughout construction to monitor and maintain the sensors. Designing the sensor network took a great deal of planning, including deciding the location of stations. Many were placed on rooftops or secure public structures and most were covered by steel cages. In recent years, technology for construction project monitoring has advanced and become a specialty of surveying technology.]]></description>

      <title>A strong foundation for growth</title>
      <link>https://trid.trb.org/View/1280975</link>
      <description><![CDATA[The city of Fort Collins and the town of Windsor in Colorado rely on the intersection of Interstate 25 and Colorado State Highway 392 for their economic growth. Nearly all traffic in Windsor passes through the intersection, and it is often used as an alternate access point to Fort Collins. By a continued growth model, it is estimated that traffic will double or triple by 2030, which necessitated plans for an interchange to be built. In order to build an interchange, reconstruction on several major highways was required. Work began on the interchange in 2011. Fort Collins and Windsor worked with the Colorado Department of Transportation to find solutions for the challenges of construction. Challenges included dealing with local wildlife and alleviating current traffic congestion. The new interchange has improved traffic, offering access to Windsor and Fort Collins.]]></description>

      <description><![CDATA[In 2001, an earthquake damaged sections of the Alaskan Way Viaduct in Seattle. The viaduct was already showing signs of aging, and the earthquake caused sections to sink by several inches. A tunnel has since been built to connect to a mile of new highway at the southern end of the city. Once the tunnel is opened to traffic, the downtown waterfront sections of the viaduct will be demolished and replaced with a new Alaskan Way surface street. The design and development of the new roads was part of an extensive planning project that looked at over 90 design alternatives with various combinations of elevated roads, surface streets, bridges, and tunnels. Major goals for the replacement plans included opening access to the waterfront and keeping traffic moving. Arriving at the finalized plan involved 3D digital modeling and public outreach.]]></description>

      <description><![CDATA[The Massachusetts Department of Transportation (MassDOT) replaced fourteen bridges on Interstate 93, which required closing half the lanes for ten weekends in summer. The project, known as 93 Fast 14, condensed four years' worth of construction into one construction season. When construction work was underway, the interstate was functioning at half of its normal capacity, which meant that a number of vehicles had to be diverted. This project required a great deal of work from MassDOT's communications staff, who kept the public informed without funding for advertising. Methods for sharing updates about the project included fliers posted on buses, posters at rest areas and offices, and handing out information cards at toll booths. The team also used social media and a central project website. On the roads, variable message signs were used. The communications department kept the public engaged with the project throughout its development.]]></description>

      <description><![CDATA[The city of Memphis, at the widest point of the Mississippi River, is ideally positioned to handle boat traffic.  This article describes Memphis’s new Beale Street Landing, which offers a world-class docking facility for passenger boats.  The landing also features a terminal building and public park.  The construction of the landing featured several civil engineering challenges, including a project site that was submerged regularly due to the yearly river stage cycle and a complex bank stabilization effort.  Because the landing is designed to accommodate the changing nature of the river, it should serve the needs of the city for many years.]]></description>
