This work aims to demonstrate the feasibility of fully preserving the historical heritage at the same time reordering the cities and their traffic.

This paper describes the sustainable solution designed for the landscape change required and to maintain the bridge integrity by excavating under the pier with the maintenance of traffic during its execution.

It is concluded that the elimination of urban motorways on the surface often leads to the excavation of tunnels under the existing buildings, with little coverage in most of them. This complicates the implementation of burials in cities with an important historical heritage, which must be given conservation priority in the choice of technical solutions.

The Segovia Bridge over the Manzanares River, the oldest bridge in Madrid, was built in the 16th century. With the burial of the M-30 motorway, it has been necessary to build a tunnel immediately under one of the bridge piers, practically without lining between the foundations and the upper slab of the tunnel.

Given the mixed evidence on the relationship between internationalisation and firm performance, the purpose of this study is to investigate the effect of internationalisation on the financial performance in the setting of a matured and stagnant market, the global automotive industry.

The study uses 37 automotive manufacturers covering from 2000 to 2015. Panel regression analyses were used to estimate the relationship between four financial performance variables (return on equity [ROE], return on asset [ROA], return on capital [ROC] and return on sales [ROS]) and three main independent variables (foreign assets to total assets [FATA], research and development intensity [RNDi], advertising intensity [ADVi]), controlling for product diversification, firm size, age and risk.

The findings reveal that automotive firms with a lower FATA ratio, lower RNDi and higher ADVi tend to achieve higher financial performance. However, the intensity of product diversification does not influence the financial performance of global automakers. Ceteris paribus, larger firms in terms of market capitalisation and new entrants into the market tend to have higher financial performance relative to smaller and older firms.

This study contributes to the literature first by examining the relationship between internationalisation and firm performance in the setting of a matured market, i.e. the automotive industry. Secondly, the paper uses a multinational sample at a global level; and third, it analyses financial performance on a comprehensive basis via four measures, namely, ROA, ROE, ROC and ROS, as the dependent variables.
