Impacts of Crossing Infrastructure on Land and Real Estate Development: A Case Study of Pathum Thani 3 Bridge, Pathum Thani Province

Abstract

Pathum Thani Province, located on the metropolitan fringe, plays a key role in supporting Bangkok’s urban expansion. Residential development trends indicate that infrastructure significantly influences land use and real estate development. This research analyzes the potential and constraints affecting land and property development and forecasts the impacts of three types of crossing infrastructure: intersection, overpass, and underpass. The study focuses on the proposed multi-level overpass extension from Pathum Thani Bridge 3, which spans the Chao Phraya River and is managed by the Department of Highways. This project serves as a critical connector in the regional transportation and economic network. The study area is defined at the intersection with Road 307, a major arterial road in downtown Pathum Thani. A mixed-methods approach is employed, integrating quantitative and qualitative data, content analysis, and expert interviews with urban planners, real estate developers, land officials, architects, and local residents.

Findings reveal that each infrastructure type distinctly influences land use patterns, property values, and the urban environment. Road infrastructure shows the highest development potential due to its capacity to support diverse land uses and stimulate property value growth. The underpass ranks second, offering moderate potential with fewer environmental impacts. In contrast, the overpass option ranks lowest, as it causes significant negative impacts such as visual obstruction, limited land accessibility, and environmental disturbances like vibration. These drawbacks hinder surrounding development and restrict the continuation of commercial and residential uses.
