1. The overall quality of many of our bridges leaves much to be desired. In spite of all

technological and scientific progress, especially the predominating medium size

bridges tend to be all alike: monotonous girders, rarely reflecting their natural or

urban environment. Structural designers must resume their cultural responsibility for

a creative conceptual design and apply all their knoledge and fantasy in adding

more variety to bridge design.

!. "earings are structural assemblies installed to secure the safe transfer of all

reactions from the superstructure to the substructure. They must fulfill to basic

requirements. They must spread the reactions over adequate areas of the

substructure and they must be capable of adapting to elastic, thermal and other

deformations of the superstructure ithout generating harmful forces.

e%tremity or the load is distributed evenly all along the e%posed portion. The upper

half of the beam depth is e%posed to tensile stress and the bottom half to

able to feel the transition. 4e have installed signs at the ork location at the

sidealk level to assist in informing the travelling public not to change lanes through

this area. Shortly after the asphalt is removed, the actual roaday reconstruction ill

occur at night ith similar lane diversions thru the construction area.
