Pit stop with novel flair
New motorway toll complex in Lucca, Italy
The recently completed motorway toll complex at the Lucca exit, designed by Ettore Piras of Genoa, is seen in Italy as the first embodiment of a new generation of such facilities. Its architectural design features include a 100% steel frame, an enclosed pedestrian walkway suspended high above the vehicle passageways and an expansive roof clad totally in brown, pre-oxidised copper.
Italian motorway toll complexes are high-tech service facilities offering exceptional functionality. Yet with its exemplary toll structure near Lucca, the architectural team at Ettore Piras in Genoa has managed not only to optimise the functionality of such facilities, but has demonstrated how they can be perfected in aesthetic terms.
The hasty motorist passing through Tuscany along the Viareggio – Lucca – Florence motorway is alerted to the presence of the impending pit stop from afar by the roof of the complex, integrated perfectly into the undulating landscape around Lucca. The curved shape and the brownish pre-oxidised copper surface of the roof cladding intentionally mirror the surroundings. The 1,635 square meters of roofing rests on a frame of six tubular steel arches running parallel to the roadway with transverse load-bearing struts. Suspended below the vertex of the arches is a tubular pedestrian bridge clad in the same manner as the roof, with brown, oxidised TECU®-Oxid copper strips. In order to create an overall effect of chromatic harmony, the entire steel frame has been painted burnt sienna. The combination of the copper cladding with the natural tone reflects the dominant hues of its setting. Eleven lanes of traffic flow beneath this structure for a distance of 34 metres. The lanes pilot drivers to the tollbooths designed and constructed as mobile units to optimise their functionality. This is the first facility of its kind in Italy. This means that, depending on the traffic volume, each lane can be rapidly converted to either a fully automatic card-payment or 'telepass' gate, or to a cash payment point. Provision has also been made for ten lanes to be dedicated to passenger vehicles and small trucks, with the eleventh reserved for heavy transport vehicles. Six elliptical, large glazed openings positioned adjacently in the roof cladding run parallel to the flow of traffic, providing the motorway tunnel section and especially the overhead suspended pedestrian walkway with natural light.
Right from the initial design stages, architects chose TECU® brand copper as the roofing material for two reasons. First, the dual demands of design innovation and financial restraint called for a modern-looking complex that would not be an economic burden in terms of construction, operation or maintenance. Second, the unique chromatic effect of the material, with the gradual process of patination developing over time, seemed to fit superbly into the characteristic Tuscan landscape. In addition to its aesthetic advantages, TECU®-Oxid was the ideal solution to fulfil the demands of maintenance-free roofing combined with maximum longevity.
The pedestrian bridge extends for a total of 105 meters above the vehicle level. This tubular structure projects from beneath both ends of the roof construction, tapering off like a funnel. The tubular cladding of the end sections consists solely of copper strips, while the upper half of the remaining tube, mostly positioned beneath the protective roofing, is glazed. The funnel-shaped tapered ends are mounted on uprights, adjacent to an open staircase on one side and to the service building access on the other. The footbridge assumes special significance in the overall construction design as the tollway complex has been assigned a new and additional transit function. During the course of imminent commercial and industrial development in the surrounding area, a large car park is to be constructed next to the complex, from where visitors and employees of the local companies will be able to reach their destinations on foot. It is within this context that the footbridge will really come into its own.
The architect Ettore Piras began his professional career after completing a degree at the University of Genoa in 1978. In addition to architectural and municipal planning consulting services, the firm has devoted its time to projects such as the Sant’Agostino Theatre in Genoa and the C. Sivori Theatre in Finale Ligure. Since 1995 they have completed a series of motorway service facilities for the COALPA-SALT company. The architectural firm was the recipient of a prize for the Lucca motorway toll complex in the TECU® Architecture Awards 2002, a bi-annual competition organised by the manufacturing company KME to showcase outstanding architectonic achievements using TECU® building materials. The jury deemed the toll complex to be an exceptional example of a new approach to the design of buildings previously dictated primarily by functional concerns and blatant pragmatism. The structure inspires with its elegance and its imaginative interpretation of functionality, with copper being utilised as the building material in a consistent yet innovative manner.
