Mandell - Good plan. 610 to 288 should work.
Fellow COOGS - I highly recommend avoiding the shut down area of I-10. I-45 south and I-69 south as well as north for both will be terrible. Montrose to Elgin is an option. From Galleria area 610 south loop to Scott is an option. 610 south loop to 288 to McGregor or Elgin is an option.
Northside COOGS (Spring / The Woodlands etc.) Loop 610 around eastside to south loop to Gulf Freeway. Loop 610 to Lockwood and take Lockwood through town to Polk then to Scott.
Elysian from Hardy street is closed until June 2019 and the reason I-10 is closed is they are tearing down the bridge on Elysian over I-10.
