Major Structures Overview – Retaining Walls

Major Structures Overview – Retaining Walls I-11 - Replace wood lagging with precast concrete

Major Structures Overview – Retaining Walls MSE Walls

Major Structures Overview – Retaining Walls CIP walls with a precast alternate

Major Structures Overview – Retaining Walls CIP walls without a precast alternate I-13-2 Needed a crashworthy wall at Mooberry, and the moment slab would have complicated access to utilities.

Major Structures Overview - Bridges

Major Structures – Lowest level

Major Structures – Lowest Level FRA-70-14.98 – Built for traffic in a future phase

Major Structures – “Tunnels” FRA-70-14.98 – Built for traffic in a future phase

Major Structures – Lowest Level FRA-70-14.79 – Partially built due to sight distance underneath

Major Structures – “Squiggle Bridge” FRA-70-14.61 – Complex Structure • Large skew • Haunched profile • Curved ends • Staggered cross frames Approach slab and rear abutment were constructed in a previous phase.

MAJOR STRUCTURES I-70 over Parsons Avenue FRA-70-14.93 L&R – WB deck to be built in a future phase.

BRIDGE ENHANCEMENTS I-70 over Parsons Avenue Parsons Ave. Bridge

ITS – Both ODOT FMS and Columbus CTSS Columbus CTSS N • Down time is only allowed a few hours one day per month • Currently Columbus is booking ahead 4 months Temporary A and Temporary B • Temporary A is the result of the Livingston C project being behind schedule. Coordinate with Livingston C project. • Temporary B is long term temporary after PID 105322 Livingston C Pre-emption to be non-performed

Drainage Upcoming Addenda Ref 168 – 60” will be expanded to other methods besides jack N and bore with steel encasement A pay item reference for Item 503 will be added for shoring bore pits Catch basin will be specified as cast in place.
