Claim 8:
9. A method of installing a bridge system, the method comprising:
a) delivering components (a)(i)-(vi) to an installation site:
i) one or more load-bearing, regular precast pocketed L-walls, each having a stem, a forebase, and a hindbase, with two pockets in the stem in a hindbase side of the stem;
ii) a load-bearing, right-sided irregular precast pocketed L-wall, having a stem, a forebase, and a hindbase, with two pockets in the stem in a hindbase side of the stem;
iii) a non-load-bearing, right-sided irregular precast non-pocketed L-wall;
iv) a non-load-bearing, left-sided irregular precast non-pocketed L-wall;
v) a load-bearing, left-sided irregular precast pocketed L-wall, having a stem, a forebase, and a hindbase, with two pockets in the stem in a hindbase side of the stem;
vi) a plurality of double-T members arranged and fastened together in at least two adjacent rows, with an equal number of double-T members in each row, each double-T member having a pair of webs, a span, and two flanges, and forming a plurality of webs, each of the plurality of webs having a proximal end and a distal end resting in one of the pockets;

b) delivering a plurality of precast foundation slabs to the installation site;
c) positioning the components (a)(i)-(vi) on the plurality of precast foundation slabs;
d) backfilling over bases of components (a)(i)-(v);
e) positioning each of the plurality of precast, prestressed concrete double-T members adjacent at least one other of the plurality of precast, prestressed concrete double-T members, where the proximal ends and the distal ends of the plurality of webs of the plurality of precast, prestressed concrete double-T members are positioned in respective pockets; and
f) connecting each of the plurality of precast, prestressed concrete double-T members to at least one adjacent one of the plurality of precast, prestressed concrete double-T members, such that
i) the one or more load-bearing, regular precast pocketed L-walls are proximate a middle of the bridge system;
ii) the load-bearing right-sided irregular precast pocketed L-wall has one edge positioned adjacent and fastened to a mating edge of the non-load-bearing left-sided irregular precast L-wall;
iii) the non-load-bearing right-sided irregular precast L-wall has one edge positioned adjacent and fastened to a mating edge of the load-bearing left-sided irregular precast pocketed L-wall; and
iv) the one or more load-bearing regular precast pocketed L-walls form first and second edges, the first edge positioned adjacent and fastened to a mating edge of the load-bearing left-sided irregular precast pocketed L-wall, and the second edge positioned adjacent and fastened to a mating edge of the load-bearing right-sided irregular precast pocketed L-wall.
