I-64 Interstate and Bridge Rehabilitations (Harrison County, IN) | HMB Professional Engineers, Inc.
I-64 OVER BLUE RIVER: This (119’, 148’, 119’) three span composite steel girder bridge carries I-64 traffic over Blue River. The 10 year old existing approach slabs were exhibiting longitudinal and transverse cracks. They were replaced with new full width approach slabs. The existing concrete barriers received surface seal from the gutter line to the drip notch. TGB type guardrail transitions and TBC barrier wall transitions were installed adjacent to the new approach slabs and to transition to the new roadway guardrail. The interstate maintenance of traffic scheme utilized crossovers for the entire project length.
I-64 OVER GETHSEMANE CHURCH ROAD: This (38’-3”, 39’, 38’-3”) three span composite pre-stressed concrete I-beam bridge carries I-64 traffic over the named county road. The existing approach slabs were replaced. The existing aluminum railing did not meet safety and design criteria and therefore was replaced with new standard concrete railing. The deck was milled and received a latex modified Portland cement concrete overlay. The last 5’ of the deck slab was removed including the entire mudwall, top of wingwalls and diaphragms. The ends of the pre-stressed concrete I-beams were encased to make them semi-integral with the type 1A joints at the approach slabs. The interstate maintenance of traffic scheme utilized crossovers for the entire project length.
SR 135 BRIDGE OVER I-64: This (78’,90’,90’,62’-6”) four span welded steel girder bridge carries SR 135 traffic over I-65 at exit 105 in Corydon. The existing approach slabs were replaced. The existing aluminum railing did not meet safety and design criteria and therefore was replaced with new standard concrete railing. The deck was milled and concrete patching done as needed. The deck then received a latex modified Portland cement concrete overlay. For south abutment 2, the last 5’ of the deck slab was removed including the entire mudwall and top of wingwalls. The ends of the welded steel plate girders were encased to make them semi-integral with the type 1A joint used at this location. The north abutment 1 had the finger joint removed and replaced with a 4” neoprene SS joint. Bearings were replaced with new steel risers and neoprene pads. A 4 phase traffic scheme was used to maintain traffic and constantly keep two lanes open in the southbound direction.
