At present, the construction of the express, semiring bypass of the Bydgoszcz agglomeration along expressways S5 and S10 is coming to an end. Current development plans do not predict transforming this semiring bypass into a full ring bypass, which could be achieved by building its eastern part, hereinafter referred to as the Eastern Bypass of Bydgoszcz (EBB).Due to the above, the aim of this article was to examine whether the construction of the EBB would make sense, and if so, what variants of the route of such a bypass are possible and which variant seems optimal. This consideration is therefore a simplified feasibility study of the investment in question.The basis for such analyses was a description of the existing condition of the agglomeration, in particular the condition of urban development, transportation and environment, as well as the already developed development plans.To assess the purposefulness (reasonability) of the investment, a method of comparing the features of such an investment with possible theoretical models of the Bydgoszcz agglomeration, mono-centric or bi-centric, was adopted. The results of such an analysis turn out to be positive, namely the completion of the eastern Bydgoszcz expressway bypass will be beneficial due the compliance of the EBB with both of these versions of the agglomeration model.A multi-criteria analysis method was adopted when selecting the EBB location from the five technically, economically and environmentally feasible bypass route variants that had been established previously. These variants were ordered according to an increasing distance from a city centre and named after the housing estates the bypass will pass by, i.e. “Eskulapa”, “Bohaterów”, “Stary Fordon”, “Ostromecko” and “Rafa”. 6 criteria were adopted in the multi-criteria analysis, namely urban, transport, functional, economical, ecological and social criteria, wherein due to the preliminary nature of the analysis, the simplest version of this method, called scoring, was adopted. As a result, it was determined that the “Rafa” variant, located farthest from the centre of Bydgoszcz, would be the optimal variant. The “Ostromecko” variant, also located far from the city centre, may be considered as an alternative variant.Taking into account the preliminary nature, the results of the above analyses are burdened with high uncertainty and may change in any further analyses.
