The whole bridge was limited to one lane each direction where there is normally four lanes of heavy traffic each direction.

Has that been confirmed? Even 2 days later i've heard conflicting accounts, 1/2 those saying 2 lanes were open per direction (4 total), and the other half saying only 1 lane per side(2 total). Could it be the reason for the confusion was that while parts of the collapsed section was down to 2 lanes, others were still at 4?

There were two lanes going in both directions. It would be quite rare for a major freeway to be down to one lane only in each direction during rush hour. (Sometimes they do it on the weekends.)

Road or bridge construction control varies hour by hour, I would think - and at Rush Hour usually they make necessary adjustments. Probably not a conflict - just a time difference.
