| Design/build laws. |
- Change Oklahoma laws to allow for design build. One prime contractor and design as you go. Contractor decides how he can speed up the construction.
- Design and construction are done concurrently.
|
- Law must be changed. Consultants are nearly under contract already so contracts need to be modified or cancelled.
|
| Standardize. |
- Simplify design and construction. Bridges, bridge beams, and storm sewer (prefabricated inlets). Inlets could be oversized and walls could be designed for different height ranges.
|
|
| Railroad construction. |
- Move railroads out of corridor as soon as possible.
|
- Early coordination and use existing relationships to expedite railroad issues.
|
| Construction sequence. |
- 1Railroad.
- Center section drainage channel/box. Move dirt from excavated sections to future fill areas.
|
- Material may not be suitable for embankment.
|
| Railroad exchange tracks. |
- How will the UP/BNSF exchange contracts affect the project?
|
- This subject was not discussed but the concern was raised.
|
| Calendar days. |
- Use maximum rate for calendar days with incentives. Based on user delays.
|
|
| Request testing. |
- Request geotechnical, hazardous waste and ground water testing. Begin with the center section since those projects are on the critical path.
|
- Time to initiate contracts.
|
| Start of construction. |
- Begin all construction at the same time (giving consideration to street closings).
|
- Possible overloading of consulting engineering firms.
|
| I-40/I-35/I-235. |
- Look at convertibility of interchange. Possibly use CD roads. Investigate impact on current project.
|
- Need detailed planning of interchanges, which would take more time than the current plan would allow.
|
| Shields interchange. |
- Remove Shields interchange in exchange for a Robinson interchange.
|
- City of Oklahoma City may be resistant to this.
|
| Robinson interchange. |
- Make Robinson a full interchange (tight diamond) instead of Shields. Improves driver expectability and weave distances with I-40/I-35/I-235.
|
- Need to improve Robinson Avenue between the new I-40 and the new Boulevard.
|
| Boulevard eastbound to I-40 eastbound. |
- Revise ramp from loop ramp to a CD road or a higher speed ramp.
|
|
| Eastbound Frontage road. |
- Remove eastbound Frontage road between Pennsylvania and Western. Consider auxiliary lane between Pennsylvania and Western. Use local streets to access the trails and river improvements.
|
- Resistance from the City of Oklahoma City and the local community.
|
| I-40/I-44. |
- Look at convertibility of the interchange. Investigate impact on current project.
|
- Time needed to complete design.
|
| Operational analysis. |
- Review operational aspects (weave distances) on all ramps.
|
- New contract with ODOT to review the operational analysis.
|
| Traffic. |
- Review traffic analysis to confirm operational issues.
|
- New contract with ODOT to review the traffic analysis.
|
| Hazardous materials remediation. |
- Insert hazardous materials remediation into contracts to facilitate quicker response and remediation when hazmat sites are discovered.
|
- State agency may choose to complete the remediation.
|
| PGL and point of rotation. |
- Consider moving the PGL and the point of rotation to the crown (two lanes over from the median).
|
- The point of rotation is already at the crown.
|
| Eliminate Agnew interchange. |
- Eliminate Agnew eastbound off-ramp, Agnew westbound on-ramp, and Agnew westbound off-ramp. Revise eastbound off-ramp to Pennsylvania via the Boulevard. Combine Pennsylvania westbound on with the westbound Boulevard.
|
- Local resistance to the elimination of Agnew interchange. May have to change the ROD.
|
| Auxiliary lanes. |
- Add auxiliary lanes between Pennsylvania and Western on both sides of the highway. Add auxiliary lanes between Western and Robinson on both sides of the highway.
|
- May be geometric constraints with the UP railroad.
|
| I-40/I-35/I-235 interchange deletions. |
- Eliminate Reno to Byers in exchange for the current Lincoln/Byers configuration. Eliminate the Reno realignment. Eliminate proposed I-35 northbound to I-40 westbound in favor of a revised alignment.
|
- I-40 would have to be raised an additional 12 feet (approximate). Geometric and traffic constraints in revising the I-35 northbound to I-40 westbound.
|
| I-40/I-35/I-235 revised interchange. |
- Retain the current Lincoln/Byers connection.
|
- I-40 needs to be raised approximately 12 feet.
|
| I-40/I-35/I-235 revised interchange. |
- Retain the Reno to I-35 southbound ramp.
|
- New abutment needs to be further north and new beams and bridge deck on most northerly span.
|
| I-40/I-35/I-235 revised interchange. |
- Revise I-40 eastbound to I-35 southbound ramp to the south side of the Boulevard loop ramp. Add an auxiliary lane between Robinson interchange and the I-40 eastbound to I-35 southbound ramp.
|
- Vertical geometry with Byers and horizontal geometry with the lower canal at the river.
|
| I-40/I-35/I-235 revised interchange. |
- Revise I-35 northbound to I-40 westbound/Boulevard ramp.
|
- Geometric constraints (specifically, vertical geometry).
