For transit boosters and urbanists in Los Angeles, last weekend’s opening of the 6.6 mile extension to the city’s Expo Line linking Downtown Los Angeles with Santa Monica represents a capstone over a quarter century of hard-fought rail construction in a city notorious for its auto-dependent populace. Los Angeles systematically dismantled its pre-World War II Red Car system in the post-war era and did not begin rebuilding its rail transit infrastructure until in the late 1980s. Metro opened the Blue line in 1990, a 22-mile light rail route linking Downtown Los Angeles with Long Beach. Since then, the system has grown exponentially, with two subway routes, four light rail lines, and two rapid bus lines completed since. Much of the recent expansion has been funded with money collected via sales tax increases. The Metro has another such initiative, Measure R2, on the November ballot this year aiming to help the agency continue its vigorous growth. A first phase of the Expo Line opened in 2012 linking downtown to Culver City. The now-completed 15.2 mile route reestablishes rail transportation between the beach-adjacent westside communities and the region’s symbolic heart downtown by essentially reviving the route taken by the Pacific Electric Red Car service’s Air Line service that ran along the former Atchison, Topeka, and Santa Fe right of way between 1908 to 1953. The new line is expected to take around an hour end to end, about the same amount of time it takes to drive in good traffic. The Expo Phase II project was constructed via a design-build partnership between Skanska USA and Rados Construction Inc. and was administered by Expo Authority, the independent agency created by Metro to build the line. Skanska USA tapped Parsons Brinckerhoff to design the route’s tracks, stations, and bicycle facilities. Parsons Brinckerhoff also designed 24 at-grade and above-grade intersections for the line. Celebrations took place at each of the seven new stations last weekend and Metro offered free fares on Friday and Saturday to commemorate the completion of the new line. The much-hyped weekend saw so many Angelenos flock to stops along the route that service got backed up as enthusiasts and skeptics alike rode rail transit to the beach for the first time in sixty years. But in perhaps a sign the difficulty Metro faces in changing L.A.’s car-dependent culture, service ground to a halt for nearly two hours Monday morning when a drunk driver drove onto the Expo Line’s tracks along an at-grade run of the line near downtown, snarling the line’s first weekday morning commute.

Here’s Philadelphia’s ambitious plan to build a neighborhood over a railyard on the Schuylkill River
Cap and trade agreements are a standard tool in the climate change fight. Philadelphia, in collaboration with an urban design team led by SOM, is getting in on the game. Recently revised plans for the 30th Street Station and surrounding neighborhoods call for capping 70 acres of Amtrak and SEPTA-owned land, trading the underutilized space for a mixed-use neighborhood, parkland, and three pedestrian bridges across the Schuylkill River, linking University City with Logan Square and Center City. SOM partnered with Parsons Brinckerhoff, OLIN, and HR&A Advisors on the $5.25 million study. Through citizen input, the design team developed three iterations of the plan, all of which were presented and debated at a December 16th meeting, PlanPhilly reported. The study reviews land use over 175 acres, 88 of which are owned by Amtrak and SEPTA. The main project partners are Amtrak, Brandywine Realty Trust, Drexel University, Pennsylvania Department of Transportation (PennDOT), and SEPTA, along with twelve other stakeholders. Once adopted, the plan will guide the area's development through 2040. In addition to the capping and bridges, all three plans propose doubling the size of Drexel Park, boardwalks, a river overlook, and a bus terminal. There will be two more public meetings on the plan in spring and summer 2016.
HOK’s ARTIC, Anaheim's high speed rail train station which AN featured today, is as much a story about technology and engineering as it is about high design. Slated to achieve a LEED Platinum rating, ARTIC is the product of an integrated, multidisciplinary BIM design process where key decisions about technology and engineering were brought into the design process from the beginning to achieve a high-tech, high-performance, and high-efficiency building. The building’s curved diagrid geometry, rationalized using CATIA, is like a contemporary reboot of the glass and steel structures that defined iconic terminals like Philadelphia’s Broad Street Station and New York City’s original Penn Station. The parabolic shell design was also utilized for its structural efficiency and for its environmental properties. For efficiency, the design team decided to go with ultra-lightweight ETFE pillows (1/100th the weight of glass). This allowed for significant reductions in foundation size and structural member dimensions. ARTIC is currently the largest ETFE-clad building in North America, with over 200,000 square feet of the high-tech material covering most of the building’s long-span shell. The ETFE system also helps to regulate heat gain and maximize daylighting while maintaining an environment that utilizes a mixed mode natural ventilation system. The building’s shape and translucent ETFE envelope work in concert with a radiant heating and cooling slab system in the public areas (optimized HVAC is used in office and retail spaces) to produce a microclimate through convection currents. This makes it possible for the building to be naturally ventilated most of the time. Heat rises and escapes through operable louvers at the top portions of the north and south curtain walls.
Cleveland's lakefront attractions and downtown have long been estranged neighbors, not easily accessed from one another without a car. The city and Cuyahoga County plan to fix that, offering a 900-foot bridge for pedestrians and bicycles that will hop over railroad tracks and The Shoreway, a lakefront highway built in the 1930s. The $25 million bridge takes off from the downtown Mall, touching down between the I.M. Pei–designed Rock and Roll Hall of Fame and the Great Lakes Science Center, designed by Boston's E. Verner Johnson. Another Bostonian is heading up design duties for the new bridge. Miguel Rosales' firm Rosales Partners hatched three design schemes with the help of Parsons Brinckerhoff. The final design has not been selected, and regional officials say it will come down to community input. Construction is expected to begin May 2015, wrapping up by June 2016. But before that, public authorities are seeking comment from the bridge's eventual users by hosting a free public meeting from 6:00 to 7:30 p.m. on Thursday, November 13, in the County Council chambers on the fourth floor of the county administration building, 2079 East Ninth Street, Cleveland. All the options are visually striking. Whether suspension, cable-stayed, or arched, the bone-white bridge wends through renderings made public last week, framing the Cleveland Browns' lakeside FirstEnergy Stadium. As the Cleveland Plain Dealer's Steven Litt wrote, the bridge fulfills a longtime goal of planners and urbanists in northeast Ohio:
Creating a bridge from the Mall to North Coast Harbor and lakefront attractions including the Rock Hall has been something of a holy grail in Cleveland city planning for nearly two decades. Yet until now, the city has been unable to mobilize support and fund the project. The city failed three times in recent years to win a federal grant for the project under the TIGER program, short for Transportation Investment Generating Economic Recovery.But now, Litt wrote, the city and county each agreed to kick in $10 million, which led the state to close the $5 million gap. A 2013 city-county partnership and the news that Cleveland would host the next Republican National Convention apparently provided the incentive they needed to take on the project, which officials said will be complete by the convention in 2016. The three design options are as follows: The suspension bridge option: The cable-stayed option: The arch option:
In one of the few towns where the AIA has serious pull, the AIA San Francisco has named Jennifer Jones as its new Executive Director. Longtime HMC principal Kate Diamond has left her position and is looking for a new job. While it pales in comparison to the news that AECOM has merged with URS, forming the biggest firm in the galaxy, WSP has bought “global design giant” Parsons Brinckerhoff for $1.35 billion. That’s no joke either. Finally, after more than six years of waiting, SOM has begun work on its massive redevelopment of the WWII-era housing development, Park Merced. In San Francisco that’s like waiting for fifteen minutes.
In response to Hurricane Sandy, the Department of Housing and Urban Development (HUD) launched the Rebuild by Design competition to develop strategies to increase the resiliency of urban and coastal areas in the face of extreme weather events and climate change. According to HUD's website, the goal of the competition is "to promote innovation by developing regionally-scalable but locally-contextual solutions that increase resilience in the region, and to implement selected proposals with both public and private funding dedicated to this effort. The competition also represents a policy innovation by committing to set aside HUD Community Development Block Grant Disaster Recovery funding specifically to incentivize implementation of winning projects and proposals. Examples of design solutions are expected to range in scope and scale—from large-scale green infrastructure to small-scale residential resiliency retrofits." The shortlist of 10 teams—including architects, landscape architects, university groups, developers, engineers and others—has been announced.

The Port Authority Board of Commissioners has endorsed a study to investigate options to accommodate growth in bus commuting to and from midtown Manhattan. The authority hired Kohn Pedersen Fox and Parsons Brinckerhoff to craft a long-term master plan to improve interstate public transit services and reduce the impact of interstate buses on nearby communities. The plan will potentially replace the Port Authority Bus Terminal in Manhattan, which has reached capacity and is in need of improvements. The comprehensive plan for the bus terminal, which is utilized by approximately 8,000 buses and 225,000 travelers daily, includes a state-of-good-repair investment program and new bus staging and storage facilities on Manhattan’s west side. The scheme has been designed to improve bus operations and limit the amount of buses idling on city streets. By tackling specific infrastructure needs, the Port Authority will make certain the terminal remains a central part of the interstate transportation network. “The development of a Master Plan underscores the Port Authority’s commitment to make the Bus Terminal a world-class facility and bus transit the most reliable mode of access to midtown Manhattan,” said Port Authority Chairman David Samson in a statement. “While the Port Authority has already begun the work of revitalizing the Bus Terminal… this comprehensive approach is the best way to ensure the Bus Terminal keeps pace with future passenger growth over the next fifty years.”
In September, AN reported on the three proposals to replace Los Angeles' iconic but crumbling Sixth Street Viaduct by HNTB, AECOM, and Parsons Brinckerhoff. The three teams have notably added pedestrian amenities and adjacent lush landscaping to the 3,500-foot-long cable-stayed span. While the renderings were compelling for each design, these video renderings fly the viewer in and around each proposal for a more detail view of what might soon be built in LA. Take a look.

The Los Angeles Bureau of Engineering has announced three finalists in an international design competition for the $401 million Sixth Street Viaduct Replacement Project. The three finalists—AECOM, HNTB, and Parsons Brinckerhoff—will be asked to design an “iconic” cable-stayed bridge across the LA River between the LA Arts District and Boyle Heights. The project is complicated by overhead high voltage lines, a change of alignment that will remove a kink in the roadway, and numerous right of way and jurisdiction issues near the river. The bridge—one of the city’s most famous structures and a frequent subject of film crews for commercials and movies—is dying a slow death from “concrete cancer” (aka, Alkali-Silica Reaction), much to the chagrin of preservationists who fought for years to save the structure. The city culled ARUP, Parsons, and SOM from the competition before advancing to the final stage. The finalists will launch a citywide tour or sorts to present their proposals for the replacement project in September. The full schedule for the proposal presentation is available here. A final decision about the winning design team is expected in October.
We learn from our friends at Curbed that Los Angeles' Sixth Street Viaduct Competition, replacing one of the most famous—and fragile—landmarks in LA, has a shortlist. The 3,500-foot-long, art deco span was recently deemed beyond repair, and the winner will build a $401 million, cable-stayed bridge in its place. The teams, all present at an LA Bureau of Engineering meeting last night, are AECOM, ARUP, HNTB, Parsons, Parsons Brinckerhoff, and SOM. Three of those teams will present their plans in September, with a winner chosen in October.
