“A new Belt for Brooklyn”—the five mile Belt Parkway reconstruction project
Published in Khaled M. Mahmoud, Asset Management of Bridges, 2017
D. Hom, W. Ferdinandsen, P. Dombrowski
The first construction project in the Belt Parkway program was the “Belt 1” package of the bridges over Paerdegat Basin, Rockaway Parkway and Fresh Creek Basin. This 2.12 mile section of the parkway between the Pennsylvania Avenue interchange (Exit 14) and the approximate midpoint between Paerdegat Basin and Mill Basin, included the following elements common to all the bridges in the program: Complete removal of the existing bridge superstructures and substructures, including the abutments and wingwall, and construction of new bridge superstructures and substructures;Construction of new approach slabs, and new approach and connecting roadways between the bridges;Installation of concrete median barrier along the entire project limits and new timber guide railing on the approach roadways;Installation of temporary and permanent bicycle/pedestrian paths, including timber rail fence;Installation of new street lighting, drainage facilities and overhead sign structures;
Design and construction of the new Frederick Douglass Memorial Bridge
Published in Khaled M. Mahmoud, Risk-based Bridge Engineering, 2019
The $442 million project is the largest construction project in the District’s history. In addition to replacing the existing Frederick Douglass Memorial Bridge, the project also includes improvements to South Capitol Street, I-295 and Suitland Parkway. The multifaceted project consists of the refinement/redesign of the horizontal and vertical alignments of 11 local roads; Interstate I-295 widening including reconstruction of three bridges over Howard Road, Suitland Parkway and Firth Sterling Avenue; five Interstate ramps; the I-295 and Suitland Parkway Interchange; and two traffic ovals to maximize the corridor’s efficiency as shown in Figure 2.

The Queens Interchange of the Whitestone Expressway and the Cross Island Parkway, which feeds the Queens Approach to the BWB, was also investigated to determine whether the current interchange can provide access to either a second level on the bridge or a widened bridge. It was determined that the interchange does not need significant modification if the bridge is widened. However, if a second level is added to the bridge, the interchange must be significantly re-configured to provide access to both levels of a two level BWB without operational restrictions.
Improving cycling environment in a Green Park based on the post-occupancy evaluation method

With the progressing construction of the park, more and more cities have begun to integrate existing detached park resources with the surrounding area and are also determined to construct of the urban park in the local area. The green path influences and promotes cycling that has now become a challenge for sustainable urban mobility in many cities where this mode of transport carries little weight (Campos-Sánchez, Valenzuela-Montes, and Abarca-Álvarez 2019). The indirect emission intensity effect was a leading contributor to change of carbon emission (2017). Greenway, developed from the Parkway, has become the focus of provincial and urban construction after 2005. In the last a few years, cycling mobility has been growing rapidly (Di Mascio et al. 2017; Ritchie 1998). Cycling activities have been used parks or other public places as active venues, and bicycles are used for commuting and leisure time activities (Bíl, Bílová, and Kubeček 2012; Han, Meng, and Kim 2017). Leisure cycling has the characteristics of popularity and adaptability, and it has unique advantages in outdoor sport.

Cartridges were again deployed alongside canisters in October and November 2016 on the roof of the SEEC building on the University of Colorado Boulder’s East Campus. This site is ≈ 100 m from Foothills Parkway, a major thoroughfare for commuters moving north or south through Boulder. Cartridges and canisters were deployed for 3 day-periods on 10 occasions. The deployed cartridges contained 27 mg of Carboxen 1000 adsorbent and were conditioned for 20 hours at 350°C with 25 mL min−1 N2 flow. Linear correlation results for cartridge with canister data comparisons (PCCs, and p-values, median RSDs, and median RSDRs) are summarized in Table 9. In Figure 7, results from the 2016 campaign are placed side by side with the earlier (2014) field study. Relatively poor correlations were found for ethane and alkenes across all sampling periods. Significantly better results, with PCCs > 0.75, were obtained for propane, n-butane, i-pentane, and n-pentane. PCCs improved in the 2016 campaign for ethane, propane, and n-butane. PCCs in the 2016 campaign were within 0.1 units of the 2014 campaigns for i-butane, i-pentane, and n-pentane. It needs to be considered that absolute analyte mole fractions ratios during the 2016 campaign were significantly lower than during the 2014 campaigns (Figure 8). Consequently, while the comparison produced similar statistical results in the 2016 and 2014 campaign, overall this represents an improvement given the lower sample mole fractions in 2016 (Figure 8).
Living suburbs for Living Streams: how urban design strategies can enhance the amenity provided by Living Stream orientated Public Open Space
Published in Journal of Urban Design, 2018
While Living Streams are an essential component of WSUD theory, their lineage can be traced to the greenway and parkway movements (Ignatieva, Stewart, and Meurk 2011), and more contemporarily green infrastructure planning (Scott Shafer et al. 2013). In these movements a ‘system of parks, greenways and undeveloped open spaces’ were and are considered ‘integral components of urban environments’ (Scott Shafer et al. 2013, 478), thinking which resonates with the Living Stream concept.
