The fast development of urban movement infrastructures has created neglected urban places in cities. This study aims to provide users’ preferences for designing lost spaces that are a by-product of elevated urban highways (UHs) and bridges to develop a conceptual model for better environmental design.

This research is conducted by a combination of both qualitative and quantitative methods. In the first phase, to explore the citizen’s environmental preferences based on the Q-sort technique and in-depth interviews, the ideas of 50 users were considered up to data saturation. The preferences of people for designs under urban bridges were extracted by content analysis in the qualitative phase. In the quantitative phase, to validate these preferences, the extracted themes and sub-themes were examined by 144 experts in design studies using the web-based questionnaire based on the first phase outcomes. The validity of the model was confirmed by confirmatory factor analysis in SPSS22 and Lisrel software.

The findings show that users’ preferences emphasize design strategies such as safety and security, physical coherence, visibility, vitality, richness, a sense of belonging and comfort to the design of lost spaces. Overall, this study highlights an empirical study into user’s needs and expectations of lost urban spaces.

This Chapter examined the development of sustainable road infrastructure in Ghana including transportation roads, and laws, regulations, and frameworks. The Ministry of Transport (MoT) and the Ministry of Roads and Highways (MRH) are responsible for the development of transportation infrastructure and related services. The Department of Urban Roads (DUR) is responsible for facilitating the movement of people, goods, and services and promoting economic and social development of urban regions. The Metropolitan and Municipal Assemblies established road centres to manage, construct, and maintain city roads, the Ghana Road Fund (GRF) was established to provide funding for the maintenance of Ghana’s road network, and the Koforidua Training Centre (KTC) was established in 2007 to provide management and project implementation staff with professional development and hands-on training. The current road length is 71,418 km, including 42,045 km of feeder roads, 14,873 km of trunk roads, and 14,500 km of urban roads. The budget for preventative maintenance is expected to rise year over year. Road infrastructure development (RID) can lead to positive societal outcomes, such as financial gains, employment opportunities, social support systems, equal rights for women and men, increased productivity, and less pollution, but it can also have unintended consequences such as deteriorating air and water quality, noise and vibration, soil erosion and sedimentation, disruption of essential services, confusion between drivers and pedestrians, changes to the landscape and habitat, and eminent domain takings. Environmental and social evaluations of development projects in Ghana must comply with several laws and regulations, and there is no unified sustainability policy or guideline in place to regulate the development of highway infrastructure projects. Resettlement is expected to help those who have been displaced by development initiatives and the Environmental Protection Agency Act of 1994 provides the authority to authorize facilities, set performance standards, and ensure compliance with standards and regulations. The Forestry Policy focusses on reducing deforestation and enhancing ecological and social commitment of forest areas, while the method for managing cultural property requires investigating and cataloguing damaged objects. Sector medium-term development plan (SMTDP) provides solutions for enhanced RID access, while the strategic environmental assessment (SEA) incorporates ecological factors into the Ghana Integrated Transport Plan. The resettlement policy framework (RPF) coordinates laws, rules, and procedures to manage road infrastructure projects and establishes criteria for determining eligibility and entitlement. The Directorate of Policy and Planning of the MRH is responsible for managing road safety and the environment, while the Directorate of Monitoring and Evaluation oversees Monitoring and Evaluation of road projects. The Ghana Highway Authority’s (GHA) four-person Road Safety and Environmental Management Unit (EMU) is responsible for addressing social and environmental issues associated with the feeder roads zone. Sustainable development (SD) has not received much attention from the Ghanaian government, with state-owned institutions prioritizing economic growth over social benefits and environmental preservation. Local governments should include a sustainability framework in their strategic planning for the successful execution of sustainable projects.
