d’Escoto has a liaison engineer and several inspectors completing the reconstruction of IL 47 at Main Street which encompassed the removal and replacement of 2 roadway bridges and multiple cell box culverts, reconstructing and raising the intersection profile of IL 47 and Main Street, resurfacing and adding a left turn lane on all four legs of the intersection, and brand-new traffic signal installation.
The existing IL 47 bridge was replaced with S.N. 045-2050 carrying 3 lanes of traffic (two through lanes and one turn lane) over Blackberry Creek using a two-stage construction safely maintaining traffic with a Temporary Soil Retention System. The new single-span bridge consists of an 8-inch reinforced concrete deck spanning roughly 82-feet long by 61-feet wide on a 10-steel beam superstructure with reinforced parapet walls extending into the approach slabs.
The profile grade elevation along IL 47 was raised 5.5-feet at the bridge location and the approach embankments were also widened to meet the bridge. The existing Main Street bridge was replaced with S.N. 045-3069 carrying 3 lanes of traffic (two through lanes and one turn lane) over Blackberry Creek using a two-stage construction safely maintaining traffic with a Temporary Soil Retention System. The new single-span bridge replaced an outdated two-span structure. It now consists of 5-inch PCC wearing surface set on seventeen precast prestressed concrete deck beams. The profile grade elevation along Main Street was raised approximately 4.5-feet at the bridge location and the approach embankments widened to accommodate the new turn lane.
